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.

COMMON ERRORS

  • 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 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. Other server settings to check are: memory allowed in php.ini file set to 250MB (or at least 128MB), and upload limit set to 10MB.

TROUBLESHOOTING TIPS

  • 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 960px wide.
  • Reset your WordPress permalinks 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.
  • Another cause of error could be in your installation of Adobe Flash. Uninstall flash on your computer and re-install a fresh copy from Adobe’s Website. Restart your browser and try again.
  • Try uploading in Google Chrome web browser
