Joomla Troubleshooter

Yesterday your Joomla site worked just fine. Today is misbehaving. And you're clueless... Right? Hey, you're not the first one having this experience. You're on the good site where you might find the cure for your problem!

This error comes back time-to-time, especially after a Joomla site is moved from one server to another. The symptoms are simple - but frightening. You try to login to the administrator interface as usual, with your well known credentials, and the login box is reloading whitouth any kind of error message and withouth letting you in. No errors in browser console, no error in the logs, and no errors even if you turn the error reporting to maximum or the Joomla debug on. You can try even the tricks described elsewhere in this site to change your admin password - that won't help.

Why? Because the cause(s) - yeah, there can be multiple causes - are different from having bad credentials! Let's see what you can do about!

ATTENTION: these tricks are qualified as core hacks, so be careful: backup, wear your lucky hat, keep your finger crossed - and take any other security measures before you proceed - you can ruin your site easily with a wrong move.

Today one of my former students approached me with his problem. He took over a site running the latest Joomla, and when tried to change the blog list views to category blog views, as the siteowner requested, the respective pages ended up with a white PHP fatal error death screen.

followed by the failing query.

Today I had to upgrade an old, Joomla 2.5.7 site to latest Joomla, everything went out fine until I had to do the first critical step - the upgrade from Joomla 2.5.28 to Joomla 3.51. Did I mentioned that server has PHP 5.6.25 withouth possibility to upgrade - at least not on short term?

ERROR: Invalid login
