500 Internal Server Error - Cornerstone

[katefair81]

I can’t launch Cornerstone. When I try to either launch Cornerstone or edit using Cornerstone, I receive a 500 Internal Server Error. I updated my license. I am not sure what the problem could be. Thank you.

Hi there @katefair81,

A 500 internal server error can be one of many things. First it’s worth trying the following:

• Deactivate all plugins. Test if Cornerstone works. If it does, reactivate plugins one by one until Cornerstone ceases working again. That will tell you which plugin is causing the conflict.
• If you have any server side caching, such as BlueHosts Varnish caching or WPEngines server side caching, temporarily disable this while testing to see if that’s the issue.
• If Cloudflare is being used, try disabling it temporarily, Cloudflares auto minification functionality can cause issues where it tries to re-minify already minified scripts.

If none of the above has worked, please ask your host for the server error log and let us know about any errors contained within.

Thanks!
