Title: [Plugin: NextGEN Gallery] HTTP error with flash-based image uploads Last modified: August 20, 2016 --- # [Plugin: NextGEN Gallery] HTTP error with flash-based image uploads * Resolved [jmek](https://wordpress.org/support/users/jmek/) * (@jmek) * [14 years, 6 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/) * NextGEN displays an “HTTP Error” message (no other details) when using the Flash- based uploader with NextGEN 1.9.1 and WP 3.3. The problem occurs whether using drag-and-drop or the “Select Files” button. Images can still be uploaded if I“ Disable flash upload,” but there goes the cool new drag-and-drop. * When the site was running NextGEN 1.8.4 and WP 3.2.1, the Flash uploader worked fine. It’s only broken since the upgrade. * And an odd thing: the HTTP error occurs only after the image has been 65% uploaded.( I am testing with images less than 20k, so it’s not a size issue.) * The error occurs even if all other plugins are disabled. * [http://wordpress.org/extend/plugins/nextgen-gallery/](http://wordpress.org/extend/plugins/nextgen-gallery/) Viewing 15 replies - 31 through 45 (of 49 total) [←](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/2/?output_format=md) [1](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/?output_format=md) [2](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/2/?output_format=md) 3 [4](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/4/?output_format=md) [→](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/4/?output_format=md) * [lwasserstein](https://wordpress.org/support/users/lwasserstein/) * (@lwasserstein) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452200) * Not sure, think it was the permissions on the gallery folder * [gdavide](https://wordpress.org/support/users/gdavide/) * (@gdavide) * [14 years ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452204) * My problem was that only admin can upload the files, other user’s can’t. I solved the problem with the same method that “simongreenland” described: with the “User role editor” by granting the “upload_files” and “unfiltered_upload” roles. * [DanPower](https://wordpress.org/support/users/danpower/) * (@danpower) * [14 years ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452208) * I have had this issue, getting ‘HTTP Error’ (no number) when uploading files, since updating my plugins. * I did the CHMOD fix (upload.php from 644 to 755) and it works now (seems to so far, have uploaded around 100 images now without the error), however my question is now, is there a security implication to this or should it be fine at 755? * I do not have users on my site, it is display-only, so I’m not sure if the user role editor workaround would help me.. * Thanks guys. * [DanPower](https://wordpress.org/support/users/danpower/) * (@danpower) * [14 years ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452209) * Spoke too soon, it was just a lucky lot of images that uploaded fine. Next lot of 10 crashed, hung for AGES on the second image then HTTP error. I left it to finish and some of the images worked and some didn’t, so I re-uploaded the ones that didn’t with the regular non-flash uploader and they worked. * So in summary I have current version of WP and plugin, no users on the site, only admin makes posts and posts images. HTTP error occurs at a rough guess on around 30% of the uploads, but the uploading will finish if I leave it long enough and some images will have been uploaded while others don’t. * [hector_luis](https://wordpress.org/support/users/hector_luis/) * (@hector_luis) * [14 years ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452210) * simongreenland method work for me * [xxxevilgrinxxx](https://wordpress.org/support/users/xxxevilgrinxxx/) * (@xxxevilgrinxxx) * [14 years ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452212) * I’ve been trying to fix this for days, to no avail.

For about 1 week ago we have NO problem with this combination/setup. “xxxevilgrinxxx” thanks for this tip !!! regards, Hans * [QuestionFox](https://wordpress.org/support/users/questionfox/) * (@questionfox) * [14 years ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452216) * I also have this problem (ERROR HTTP error. : HTTP Error. occuring when trying to upload images to the NextGen gallery) and it seems to have broken the moment I updated Contact Form 7. Temporarily disabling the Contact Form 7 plugin allows me to upload without any problems – so it definitely seems to be that plugin in my case – thanks for pointing me in the right direction! * Let’s hope they put out a fix for this – both those plugins are very popular so surely it’s affecting a lot of people. * [defke110](https://wordpress.org/support/users/defke110/) * (@defke110) * [14 years ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452217) * I found this on another topic: [Contact Form 7 breaks Nextgen Gallery Flash Upload](http://wordpress.org/support/topic/contact-form-7-breaks-nextgen-gallery-flash-upload?replies=4#post-2877429) * This will do the trick !!!

I have been fighting with this for a few weeks and was about to pull my hair out! I used CF7 and NextGEN on many sites I build. This last one has about 150 images for the gallery and I was DREADING uploading each one individually. * I concur with QuestionFox’s statement “Let’s hope they put out a fix for this– both those plugins are very popular so surely it’s affecting a lot of people”! * [ncernak](https://wordpress.org/support/users/ncernak/) * (@ncernak) * [13 years, 12 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452220) * I can’t thank you enough defke110, that did the trick!!! * cheers ☮ * [amigoaldo](https://wordpress.org/support/users/amigoaldo/) * (@amigoaldo) * [13 years, 11 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452222) * Tank you very much defke110. We only lost the time to read this topic. We tried disabling Contact-form 7 and worked. Tried with software change as you suggested, after reactivatin CF 7, and it worked. * Aldo * [whalegeek](https://wordpress.org/support/users/whalegeek/) * (@whalegeek) * [13 years, 11 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/3/#post-2452224) * FWIW, the NextGen gallery plug in has been bought by a company called Photocrati. Just announced on the NextGen website a few days ago. Big things seem to be coming, and that includes a fix for this. Which is good because it worked fine for me once my host fixed it (not knowing about the CF7 conflict) and now, unless I disable CF7 NONE of my photos will upload; before it was just a handful. * Hopefully there will be plug in updates soon! * [http://www.nextgen-gallery.com/photocrati-acquires-nextgen-gallery/](http://www.nextgen-gallery.com/photocrati-acquires-nextgen-gallery/) Viewing 15 replies - 31 through 45 (of 49 total) [←](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/2/?output_format=md) [1](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/?output_format=md) [2](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/2/?output_format=md) 3 [4](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/4/?output_format=md) [→](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/4/?output_format=md) The topic ‘[Plugin: NextGEN Gallery] HTTP error with flash-based image uploads’ is closed to new replies. * ![](https://ps.w.org/nextgen-gallery/assets/icon-256x256.png?rev=2083961) * [Photo Gallery, Sliders, Proofing and Themes - NextGEN Gallery](https://wordpress.org/plugins/nextgen-gallery/) * [Frequently Asked Questions](https://wordpress.org/plugins/nextgen-gallery/#faq) * [Support Threads](https://wordpress.org/support/plugin/nextgen-gallery/) * [Active Topics](https://wordpress.org/support/plugin/nextgen-gallery/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/nextgen-gallery/unresolved/) * [Reviews](https://wordpress.org/support/plugin/nextgen-gallery/reviews/) ## Tags * [drag-and-drop](https://wordpress.org/support/topic-tag/drag-and-drop/) * [flash uploader](https://wordpress.org/support/topic-tag/flash-uploader/) * 49 replies * 25 participants * Last reply from: [mikomai](https://wordpress.org/support/users/mikomai/) * Last activity: [13 years, 7 months ago](https://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-with-flash-based-image-uploads/page/4/#post-2452262) * Status: resolved
