Title: "Unexpected error" when uploading Last modified: August 31, 2016 --- # "Unexpected error" when uploading * Resolved [pigatrix](https://wordpress.org/support/users/pigatrix/) * (@pigatrix) * [10 years, 1 month ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/) * Hello, * I get the famous “An unexpected error occured. This is most likely due to a server misconfiguration.” while uploading. I run the latest version of NextGen Gallery and WordPress. An important aspect to mention is that I recently changed the domain of the website. The plugin worked well before. * Here’s a list of what I already tried: -Editing the permalinks -Reparing and optimising the database -Disable other plugins and custom theme -Resetting the NextGen Gallery options -Re-installing NextGen Gallery -Making sure the file and directory permissions are correct on the server -Trying to upload small sized images -Disabling AdBlock Plus -Making sure that in the NextGen Gallery options, the image directory path is correct * I’m getting pretty hopeless, is there anything else I could try? * Thanks in advance and kind Regards * [https://wordpress.org/plugins/nextgen-gallery/](https://wordpress.org/plugins/nextgen-gallery/) Viewing 12 replies - 1 through 12 (of 12 total) * Plugin Contributor [photocrati](https://wordpress.org/support/users/photocrati/) * (@photocrati) * [10 years, 1 month ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/#post-7254669) * [@pigatrix](https://wordpress.org/support/users/pigatrix/) – “Optimizing” the database, depending on how aggressively this is done, can cause some serious and potentially unrecoverable issues with NextGEN Gallery, hopefully this is not the case here. * Please try our external Reset Tool plugin here: [https://bitbucket.org/photocrati/nextgen-gallery-reset/get/default.zip](https://bitbucket.org/photocrati/nextgen-gallery-reset/get/default.zip) * To install and activate, go to Plugins > Add New … Upload Plugin To use, go to Tools > NextGEN Gallery Reset * We do not offer specific support for the Reset Tool plugin as is but it can help in many circumstances, please let us know if it does. * Thanks! * – Cais. * Thread Starter [pigatrix](https://wordpress.org/support/users/pigatrix/) * (@pigatrix) * [10 years, 1 month ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/#post-7254672) * Cais, * The reset tool didn’t seem to solve the problem. Should I delete and reinstal the NextGen Gallery? * Kind regards, Sven * Plugin Contributor [photocrati](https://wordpress.org/support/users/photocrati/) * (@photocrati) * [10 years, 1 month ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/#post-7254673) * [@https](https://wordpress.org/support/users/https/)://wordpress.org/support/ profile/pigatrix – Again, depending on the database “optimization” it may still not make any difference but you could always give re-installing a try. * You may need to go back to a complete removal of NextGEN Gallery and start over. The following might be of use if that is the case: * > This process will generally work but we recommend you have a complete fully > verified back-up of your site just in case you run into any problems: > Use FTP to remove NextGEN Gallery related folders. > Then use something like > [http://wordpress.org/plugins/wpdbspringclean/](http://wordpress.org/plugins/wpdbspringclean/) > to delete all the ngg tables.

This is most likely due to a server misconfiguration.” * The odd thing is this, if I go to do it again, the gallery I have created is not in the drop down list at the top of the add image gallery dropdown. However, if I navigate away to the Manage Gallery section I notice that it has created a gallery of the same name for each image that failed to upload, each with one image in. However clicking in to any of these galleries I just see the image cannot be displayed thumb instead of the image. * For example, if I attempt to upload 12 images to a gallery called Gallery 1, the process will fail but I will have created 12 Gallery 1 galleries all with one missing image in it. Make sense? * I am running the latest version of the Gallery and WordPress. I do already have many galleries that still work – so I guess the plug in is still working for the viewer. * Hope this ramble helps troubleshoot! * Mic * Thread Starter [pigatrix](https://wordpress.org/support/users/pigatrix/) * (@pigatrix) * [10 years, 1 month ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/#post-7254716) * In my case, there aren’t new albums created either. * Plugin Contributor [photocrati](https://wordpress.org/support/users/photocrati/) * (@photocrati) * [10 years, 1 month ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/#post-7254720) * [@r_chee](https://wordpress.org/support/users/r_chee/) – Please start your own topic so we can try to help you with your specific issue on your specific site. * See [http://codex.wordpress.org/Forum_Welcome#Where_To_Post](http://codex.wordpress.org/Forum_Welcome#Where_To_Post) * Thanks! * – Cais. * Plugin Contributor [photocrati](https://wordpress.org/support/users/photocrati/) * (@photocrati) * [10 years, 1 month ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/#post-7254721) * [@pigatrix](https://wordpress.org/support/users/pigatrix/) – Please send us a Bug Report ([http://imagely.com/report-bug/](http://imagely.com/report-bug/) … please reference this topic) so we can get a better look under the page at your site. * Please include as many details as you can about your site and the issue at hand so we can move on this as fast as possible. * Thanks! * – Cais. * Thread Starter [pigatrix](https://wordpress.org/support/users/pigatrix/) * (@pigatrix) * [10 years ago](https://wordpress.org/support/topic/unexpected-error-when-uploading-1/#post-7254742) * The problem was that I had an index.html file in my root directory.
