People still getting the 500 error, please try the following:
If you have access to the error logs on your server, please trigger the error and then send the logs to me so I can see what's going wrong. If you don't know if you have access, please trigger the error, note the time and date, then write to your web host requesting the PHP error logs for that time.
If you are able to, please go through the following procedure:
- Switch to a default WordPress theme (TwentyTen, TwentyEleven, TwentyTwelve) – do you still get the error?
- Deactivate all other plugins – do you still get the error?
- Reactivate your plugins one by one – which one triggers the error? Make a note, deactivate the other plugin, then continue on reactivating to check it's just the one plugin clashing. Let me know which plugins are clashing.
Which page are you getting the error on? Is it just the authorisation page?
@timdudley76 – What plugins are active on the site where you have the problem which are not active on the site where you don't have the problem? What themes are you running on both sites?
