The website encountered an unexpected error. Please try again later.

I 'maintain' a site for an organization and use drupal as the content engine. I rarely login, except when I am notified that a module or something needs to be upgraded to a newer version.

Unfortunately, I do not know when I last logged in, but I would say sometime over the last 30 to 45 days, to upgrade a module or maybe a theme. I did not encounter any errors, but certainly did not do any regression test, post upgrade.

Today, I logged in to update a more advanced content that I help them with and it worked fine. After finishing, I decided to check the Modules tab for any possible upgrades. When I clicked it, I get the following error:

The website encountered an unexpected error. Please try again later.

I then tried to go to the tab with the logs to find out what was going on and received the same error.

I pulled down the web log errors and found nothing (at least nothing that would cause a problem with PHP) and then checked the php error log and there's nothing in it for the last month. The last error was:

[07-Jun-2012 01:03:03] PHP Fatal error: Maximum execution time of 180 seconds exceeded in .../public_html/includes/locale.inc on line 1781

The site appears to work fine. I can update new content. But, I cannot get to the Modules or People or Configuration or Reports (I always get the error above.)

I found a tip on disabling modules, but when I ran the query, there were around 180 modules and I really have no idea which ones to disable (if there had been 20, I'd have just tried them one at a time, but it seems a bit onerous to try this same approach on 180).

Can someone provide some general steps on how to troubleshoot an issue when you don't know the last change that was done to the site and cannot get to the logs (thru the admin panel, at any rate)?

thanks,

jones
