Why am I unable to upload images in NextGEN Gallery?

Though we try our best to build NextGEN Gallery to be fully compatible with all types of server environments, there are a handful of common errors that can sometimes occur due to an incompatible server that may have some strict or insufficient permissions and settings.


  • Unable to create gallery - make sure that your server has 755 permissions set on /wp-content directory.  If your hosting environment requires higher than 755, you risk being vulnerable to hackers. This is a sign of a less supportive web host for WordPress. You should NEVER have to go as high as 777.
  • Unable to upload images - make sure that your server has sufficient permissions set for the /wp-content directory. Other server settings to check are: memory allowed in php.ini file set to 250MB, and upload limit set to 30MB or higher.


  • Try renaming the image file to be something like: trees123.jpg . Remove the extra characters and spaces in the filename, and try uploading again.
  • Re-size images before uploading to be no larger than 1920px wide and a file size no larger than 1MB. Please review our help guide on optimizing images for the web.
  • Reset your WordPress permalinks under Settings > Permalinks in your WordPress dashboard to 'post name' > save changes and try again.
  • In some cases another plugin could be interfering with your site functionality, including uploads. Try deactivating all plugins (including NextGEN Gallery) > clear your browser cache, and reload your site. Re-activate NextGEN Gallery only and try uploading again.
  • If none of the above troubleshooting tips work, try temporarily switching to the WordPress default theme, and try uploading again.
  • Try uploading in Google Chrome web browser
