Title: HTTP error Last modified: August 22, 2016 --- # HTTP error * Resolved [sepruda](https://wordpress.org/support/users/sepruda/) * (@sepruda) * [11 years, 8 months ago](https://wordpress.org/support/topic/http-error-47/) * I’ve just installed this plugin, and tried to upload a big image, which should be resized. When uploading, I get a HTTP error message, even when I disable resizing. Once the plugin was disabled, I could upload as normal. * [https://wordpress.org/plugins/resize-image-after-upload/](https://wordpress.org/plugins/resize-image-after-upload/) Viewing 9 replies - 1 through 9 (of 9 total) * [jepsonrae](https://wordpress.org/support/users/jepsonrae/) * (@jepsonrae) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376227) * What did the error message say? * Thread Starter [sepruda](https://wordpress.org/support/users/sepruda/) * (@sepruda) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376234) * HTTP error * [jepsonrae](https://wordpress.org/support/users/jepsonrae/) * (@jepsonrae) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376237) * Was there a number provided, e.g. 301, 302, 404, 500, etc? There are numerous http errors and can be caused by numberous issues. * Were there any issues reported by PHP or with a message such as “memory exhausted when trying to allocate…”. * Without specifics, it’s incredibly hard to impossible to diagnose the problem and fix it. * Thread Starter [sepruda](https://wordpress.org/support/users/sepruda/) * (@sepruda) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376238) * Sorry, it was 404. * [jepsonrae](https://wordpress.org/support/users/jepsonrae/) * (@jepsonrae) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376239) * Hmm… that’s really weird. The plugin doesn’t add any web pages to the upload process, it just injects a function into upload mechanism, so as far as I’m aware there shouldn’t be a 404 error cropping up. If you were getting a 404 error which is quite a serious one, then everyone should get a 404 error (including myself as I use the plugin on around 10 websites). * Would it be possible for you to attempt to redownload and re-install the plugin? i.e. make sure you completely delete it before reinstalling it – it’ll just be as simple as deleting the plugin folder, it won’t break anything. Perhaps you are missing a plugin file for some reason so reinstalling it will put it back. * Thanks Phil * Thread Starter [sepruda](https://wordpress.org/support/users/sepruda/) * (@sepruda) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376240) * I just deleted the plugin and did a new install, activated the plugin and the resizing option. When uploading a big image, I get the HTTP error again – although no number, so maybe I remembered it wrong. * [IJMacD](https://wordpress.org/support/users/ijmacd/) * (@ijmacd) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376283) * I too am getting this error. I’ve only just installed this plugin so can’t say if this was due to a recent update or anything. * I’ve done some quick diagnosis. I can still upload images successfully which are below the resize limit I set with the plugin. However, when I try to upload an image larger I experience similar symptoms to [@sepruda](https://wordpress.org/support/users/sepruda/). The ajax uploader fails only returning the message ‘`HTTP Error`‘. Using the browser uploader fails silently. Inspecting the request shows it was a 500 error but it too was silent. After enabling ‘`WP_DEBUG`‘ the server spat out this with the 500 response: * > Fatal error: Call to undefined function imagecreatefromjpeg() in /var/www/html/ > studio/wp-content/plugins/resize-image-after-upload/class.resize.php on line > 183 * I have ImageMagick installed on my server but not GD: * > ``` > imagick module enabled > imagick module version 3.1.2 > ``` > * WordPress is able to resize images itself, however, via the Edit Image page. * [jepsonrae](https://wordpress.org/support/users/jepsonrae/) * (@jepsonrae) * [11 years, 7 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376284) * Thanks for the great feedback. I’ll be sure to check this out. I’m investigating the wp_image_resize function that could probably replace a lot of the custom resize code and will detect automatically whether to use ImageMagik or GD. I’ll keep you posted. * [jepsonrae](https://wordpress.org/support/users/jepsonrae/) * (@jepsonrae) * [11 years, 3 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376336) * Hi, * This should now be resolved with version 1.7. I’ve completely re-engineered the plugin’s resizing methods to use WP_Image_Editor, so now if your server has ImageMagick, it’ll use that! * Sorry for the delay. Please report back if it helps. * Kind regards Phil Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘HTTP error’ is closed to new replies. * ![](https://ps.w.org/resize-image-after-upload/assets/icon-256x256.png?rev=1940740) * [Resize Image After Upload](https://wordpress.org/plugins/resize-image-after-upload/) * [Frequently Asked Questions](https://wordpress.org/plugins/resize-image-after-upload/#faq) * [Support Threads](https://wordpress.org/support/plugin/resize-image-after-upload/) * [Active Topics](https://wordpress.org/support/plugin/resize-image-after-upload/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/resize-image-after-upload/unresolved/) * [Reviews](https://wordpress.org/support/plugin/resize-image-after-upload/reviews/) * 9 replies * 3 participants * Last reply from: [jepsonrae](https://wordpress.org/support/users/jepsonrae/) * Last activity: [11 years, 3 months ago](https://wordpress.org/support/topic/http-error-47/#post-5376336) * Status: resolved
