I have had the chance to use PT a couple of times in various projects and it worked great. But for some odd reason, on a fresh install of WP 2.5.1, I couldn’t get the test thumbnail to get created. I get the same message “Cannot create test thumbnail” after having activated the Plugin and going in the settings. * ———————- * PHP version 5.2.5 Remote files Retrieve remote file is OK Dealing with remote file also requires php 4.3.0 or later GD version bundled (2.0.34 compatible) Safe mode Safe mode off Memory limit 128M Memory usage Function memory_get_usage available Set Memory limit Memory can be set wordTube Wordtube detected.

Thanks in advance. * [lucasmcdonnell](https://wordpress.org/support/users/lucasmcdonnell/) * (@lucasmcdonnell) * [18 years ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753242) * Well, I can tell you what worked for me. I went into wp-content/uploads/ and created a directory called ‘pth’, so that I now have wp-content/uploads/pth. I then right clicked on the directory, and used chmod to give write access to the directory (in the box that pops up when you chmod, just type in ‘777’, without quotes of course). * The test image was then able to be created. Hope this helps someone. * [OzBlog](https://wordpress.org/support/users/ozblog/) * (@ozblog) * [17 years, 12 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753252) * i get the same error message * Although, i didn’t change any of the info that had automatically been entered into Location Settings Options. * i also created a folder in wp-content/uploads called pthumbs and made it writable, but i still get the same message and it just shows the default question mark thumbnail in my posts. * should that folder really be called “pth” instead of “pthumbs”. i tried that aswell and still didnt work. * [OzBlog](https://wordpress.org/support/users/ozblog/) * (@ozblog) * [17 years, 12 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753254) * um, does no one really know how to fix this? * Also, my thumbs are not saving in the pthumbs folder but into the uploads folder. but even when i manually move them to the pthumbs folder they still don’t show up in the post. * [gloriagoldrea](https://wordpress.org/support/users/gloriagoldrea/) * (@gloriagoldrea) * [17 years, 8 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753298) * Did any body find the answer to this question? * I get this error: Update error: Cannot create test thumbnail. * [Billy](https://wordpress.org/support/users/billybrasov/) * (@billybrasov) * [17 years, 8 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753299) * I get the same error: Update error: Cannot create test thumbnail. * I have the pth folder maked witk 777 permitions but nothingh ,,, * [hellows](https://wordpress.org/support/users/hellows/) * (@hellows) * [17 years, 7 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753302) * the same here. nothing is working. i use the one-theme. * get this. * Update error: Cannot create test thumbnail. * [sarahd](https://wordpress.org/support/users/sarahd/) * (@sarahd) * [17 years, 7 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753305) * For some reason I had to set the thumb folder to CHMOD 755, not 777. That was for a site hosted by Dreamhost. On other hosts 777 has worked fine. * [djvibe](https://wordpress.org/support/users/djvibe/) * (@djvibe) * [17 years, 7 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753307) * i have the same problem. Although I have installed PT with minimal efforts on a Linux server I am having trouble with a Windows server running IIS. I have WP running with no other errors so far.. only PT isnt working.. * Has anyone successfully configures PT on a windows server? * Cheers, * G * [enoyad](https://wordpress.org/support/users/enoyad/) * (@enoyad) * [17 years, 7 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753308) * I had the same error.

CHMOD 777 doesn’t make any difference (I tried 755 too just in case and that doesn’t work either). * I’m wondering about this bit: * _PHP version 5.2.8 Remote files Retrieve remote file is OK Dealing with remote file also requires php 4.3.0 or later * Did something change in a PHP version between 4.3 and 5.2 that’s stopped the plugin working? * [doodlemojo](https://wordpress.org/support/users/doodlemojo/) * (@doodlemojo) * [17 years, 5 months ago](https://wordpress.org/support/topic/plugin-post-thumb-revisited-update-error-cannot-create-test-thumbnail/#post-753311) * I had the error “Update error: Cannot create test thumbnail.” with WP 2.7 and got it working following this: * 1) Created a new directory under /wp-content/uploads. Called it ‘thumbs’ 2) Did a CHMOD 775 on the new directory from step 1 ( /wp-content/uploads/thumbs/) 3) Logged to WP admin and went to Dashboard-> Settings-> Post Thumb-> Basic Options 4) Entered the following in the “Folder Name”: * wp-content/uploads/thumbs * 5) Hit “Update” (obviously) * Note: CHMOD 777 did not work so i used 755 as suggested above and got it working on ipowerweb.
