[SOLVED] Updated Drupal via Drush up command. Now I have a Server 500 error

Issue

I have a Drupal install on my local machine. Ran Drush up command to update the core files. Now I just get a Server 500 error. Before I ran drush up, my drupal installation folders permissions looked like:

drwxr-xr-x  27 uName staff 918 ...

After running drush up, they look like this:

drwxr-xr-x  29 uName staff 986 ....

I admit I am not extremely familiar with chmod/chown or how to fix this issue, but I am sure it has something to do with the folder/file permissions. Any help would be greatly appreciated.

Solution

Interesting. A few things to try:

• Visit update.php on your site (if you can get there) and run through the updates, it's possible there are some lingering
• Run a TRUNCATE TABLE cache MySQL query, and repeat for all other tables whose name begin with cache_
• Move your .htaccess file out of the site root and try to access the site again. If it works you know the problem is in there
• Check that you didn't have any custom changes in the old .htaccess file; if you did, make sure tha changes are copied across to the new file (once you've moved it back into the site root).
• After that you're really left with manually disabling contributed modules in the system table (setting status column to 0) and visiting the site again after each; that way you might be able to narrow down a rogue contributed module that is now causing a problem.

Let me know how you get on with that, if none of it works there might be more things you can try.
