Is it the number of new files and folders it’s looking for/finding? * Is there a way to process it in smaller batches? * Folder permissions are 755 [@psmits1567](https://wordpress.org/support/users/psmits1567/) * [Peter Smits](https://wordpress.org/support/users/psmits1567/) * (@psmits1567) * [6 years, 11 months ago](https://wordpress.org/support/topic/500-error-157/#post-11839486) * Hi * So the folder permissions are ok. In my experiance a lot of 500 errors are caused by a wrong entry in the .htaccess file. You could try renaming it, and test again. How many images/ folders do you have?

To turn on WordPress debugging, edit the site’s wp-config.php file and change * `define('WP_DEBUG', false);` * to * ``` define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false); @ini_set('display_errors', 0); ``` * (Be sure to change this back when you are done.) * This will allow different kinds of messages, some will not be related to Media Library Folders, to be written to a debug.log file in the wp-content folder. Now try checking for new folders and then check the debug.log file. * You can also see how many folders Media Library has already found by activating the Media Library Folders Reset plugin and viewing the Display Folder Data at the to of the page. * Also, sometimes a plugin installed on your site will add folders to your uploads folder and only store data and not any media files. If is possible that such a folder may contain many subfolders. These type of folders and their sub folders do not need to be include in the search for new folders. Media Library Folders has a list of folders to skip, which you can see in the plugin’s folders_to_hide. txt file. * If you notice any folders in your uploads directory that should not be included in the media library or media library folders, then you can add that folder name to the list; each folder name needs to be on a separate line in the folders_to_hide. txt file. And if one of these plugin related folders has already been included in the MLF’s folder tree, you can remove it by right clicking on the folder and selecting ‘Hide this folder?’ Be careful with this because if used with a folder containing media files, those files will no longer show up in the media library, but they will not be deleted from the site. - This reply was modified 6 years, 11 months ago by [AlanP57](https://wordpress.org/support/users/alanp57/). - This reply was modified 6 years, 11 months ago by [AlanP57](https://wordpress.org/support/users/alanp57/). * Thread Starter [one3rdnerd](https://wordpress.org/support/users/one3rdnerd/) * (@one3rdnerd) * [6 years, 11 months ago](https://wordpress.org/support/topic/500-error-157/#post-11839745) * Thanks for your input guys * [@psmits1567](https://wordpress.org/support/users/psmits1567/) * I tried removing the htaccess file and retried the check new folders process and I got the same result unfortunately. * [@alanp57](https://wordpress.org/support/users/alanp57/) * I added * define(‘WP_DEBUG’, true); define(‘WP_DEBUG_LOG’, true); define(‘WP_DEBUG_DISPLAY’, false); @ini_set(‘display_errors’, 0); * I then re-ran the check for new folders but no debug.log file has appeared inside wp-content. * This is the screen I see when I go to the main plugin page * > [View post on imgur.com](https://imgur.com/a/DVGV9O6) * The loading icon keeps turning and nothing shows there and sometimes this pop up appears with some html and css output. * I do have some other folders in my wp-content added by different plugins.

The only distinction between the two hosting accounts is that one is old and has CPanel and one is new and has Sitegrounds new proprietary replacement for CPanel which is a result of the fallout after CPanel’s pricing hike. * Just adding some additional info if it helps. * [Peter Smits](https://wordpress.org/support/users/psmits1567/) * (@psmits1567) * [6 years, 11 months ago](https://wordpress.org/support/topic/500-error-157/#post-11839796) * Hi * I do not think that the configuration panel is the problem. I have the impression that the environment is a bit different. Do you use the same plugins on both sites? You could try to disable all plugins except Media Library Folders. Another try could be to rename the uploads folder,and create a new uploads folder. Then test again and see what happens. If the problem is still present, then the problem has nothing to do with the contents of the uploads folder. Do both platforms run on Apache and the same PHP version? * Plugin Author [AlanP57](https://wordpress.org/support/users/alanp57/) * (@alanp57) * [6 years, 11 months ago](https://wordpress.org/support/topic/500-error-157/#post-11839810) * To add to Peter’s suggestion, deactivate Media Library Folders, run the Database Reset and then reactivate Media Library Folders.

Also I think there is a memory problem on this system. That might give you a performance poblem when selecting images to add to new pages. If all links are present the lookup of a single image will not be a problem, but handling all of them will sure not work quickly. * Plugin Author [AlanP57](https://wordpress.org/support/users/alanp57/) * (@alanp57) * [6 years, 11 months ago](https://wordpress.org/support/topic/500-error-157/#post-11845003) * Definitely there is going to be problems scanning those folders at one time. Additionally, it is likely that the folder tree will not be able handle all those folders once they are added to the folder table. There is a limit to the amount of browser memory that can hold the folder data used to display the folder tree. It may be able to hold data for about 1000 folders. It would not be possible to display a folder tree containing 7000 folders.
