Is there anything different about the server that your site is using? * Thread Starter [Red-Heart](https://wordpress.org/support/users/red-heart-1/) * (@red-heart-1) * [10 years, 9 months ago](https://wordpress.org/support/topic/invaled-argument/#post-6574952) * I’m using WAMP server on my PC, didn’t modified it but I think and I’m not sure that the problem happened because of another plugin, I had deactivated all plugins and the problem stayed the same. * – if I can modify a file or couple or maybe a string in phpmyadmin database to take the control back of the library folders the problem will be solved. * Thank you Alan for the replay and your support. * Plugin Author [AlanP57](https://wordpress.org/support/users/alanp57/) * (@alanp57) * [10 years, 9 months ago](https://wordpress.org/support/topic/invaled-argument/#post-6574967) * This seems odd. But I think windows might be case sensitive with file and paths names.

I think if any of the duplicate folders are empty when you view them in MLP, then you can delete them. * It may be that the MLP is using a URL rather than an absolute directory path when uploading a file or creating a folder in WAMP which is causing the errors. MLP tries to change the URL of the file or new folder into a absolute directory path. But I don’t know yet why this is not happening. * Plugin Author [AlanP57](https://wordpress.org/support/users/alanp57/) * (@alanp57) * [10 years, 9 months ago](https://wordpress.org/support/topic/invaled-argument/#post-6575003) * A question, what version of PHP is your WAMP using? * Plugin Author [AlanP57](https://wordpress.org/support/users/alanp57/) * (@alanp57) * [10 years, 9 months ago](https://wordpress.org/support/topic/invaled-argument/#post-6575005) * We released an update today. It does not contain any specific changes to fix your issue, but still you can give it a try. * Thread Starter [Red-Heart](https://wordpress.org/support/users/red-heart-1/) * (@red-heart-1) * [10 years, 9 months ago](https://wordpress.org/support/topic/invaled-argument/#post-6575006) * Thank you Alan, I just updated the ML+ * – the php version is 5.5.12. * – I cant delete the folders or change anything within it like rename or add, I get the error I mentioned it when I do. * I can give you a hand with this if you guide me to know where to look to modify or delete the folders entries in phpmyadmin database or where to modify the files inside the wordpress directory, because I think that another plugin had modified something and broke the ability to control those folders. * if there’s nothing to do then case closed 😉 , have a good time. * Plugin Author [AlanP57](https://wordpress.org/support/users/alanp57/) * (@alanp57) * [10 years, 9 months ago](https://wordpress.org/support/topic/invaled-argument/#post-6575008) * Red-Heart, I sure you would not be having this difficult if you were running on an actual server. If you were on a host account then I could log in an see the issue myself. But I have tested MLP on both Apache and Windows servers and resolved issues that I found on them. I also use MLP on a localhost and do not have this issue. * Yes, a plugin could be causing a conflict. * If you want to try to remove the duplicate folders then you can do so using PHPMyAdmin. First check to see what folders are actually in your uploads directory of your site. Are there duplicate folders or do these duplicates only exits in the database? Information about the folders are stored in the ‘posts’ table in records with the ‘mgmlp_media_folder’ post type. The location of the folders is stored in the ‘guid’ field. MLP adds a table to the database, ‘mgmlp_folders’, which have the post_id (the ID of the table or media attachment) and its parent folder ID( in the folder_id field). You can find the ID of a folder displayed in the MLP page by using a browser’s web inspector or firebug. You will see the folder ID in the folder attribute: folder=”folder ID”. With this information you can determine which records in the ‘posts’ and ‘mgmlp_folders’ tables should be deleted. * Thread Starter [Red-Heart](https://wordpress.org/support/users/red-heart-1/) * (@red-heart-1) * [10 years, 9 months ago](https://wordpress.org/support/topic/invaled-argument/#post-6575026) * Thank you so much dear Alan, I’m using a fresh installation of wordpress now and had exported my old work into it and the ML+ plugin working like a charm, I tested it a lot from two weeks til now beside many other plugins and found zero issues, the problem might happened because of an old low rated category image plugin I used and not compatible with my WP version, said maybe because I had deleted it and didn’t give it a try to test it again. * thanks again for your support and best wishes to you and Maxfoundry team with the next releases.
