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!

Did you had this experience? Couple of days ago I just turned on SEF and the inner pages began to act weird - images disappeared, modules misbehaved, scripts weren't loaded...

My first reaction was that I have set something wrong... or the SEF component I used have a flaw. After few days of digging I found that the issue has a much simpler cause.

Do you have some old Joomla site (pre Joomla 1.5.6)? then is very likely you will got - or already have - a site running only halfway, full of errors saying

Deprecated: Function eregi() is deprecated in somecomponent...

or

Warning: Parameter 3 to showItem() expected to be a reference, value given in /home/someaccount/www/www/joomla/includes/Cache/Lite/Function.php on line 100

 

Yeah, you might allready guessed it, the PHP 4.* end of life-cycle is wreaking havoc in Joomla 1.0 sites and some early Joomla 1.5 implementations - or even newer sites, having badly coded third party extensions installed.

Sometimes when you publish a new menu item, and everything seems to be OK, when you try to access the new menu item you just created you hit the wall: instead of the intended content you'll see the following error:

You are not authorized to view this resource.
You need to login.

Even more confusing can be the situation when a link which used to work behaves this way. The target content item is published, access rights are set to Public, and you still got this message! What can be wrong here?

Your Joomla site is hosted on 1&1? Great! ... Or not so great? Yea, I know the feeling, I had that experience too. All worked just fine (almost) until I decided to kick in the SEF engine, and use the .htaccess redirect, as I suggested elsewhere. And the disaster stroked...

It is an error which drive me crazy couple of times. It's easy to fix - but hard to detect why happening. I didn't see any good explanation which fits to each single situation I needed to handle it. There are couple of popular theories on what causes the "jtablesession::Store Failed - DB function failed with error" type of errors, but sincerely  I can not confirm any of them:

  • Flooding (Check your http access logs for access IP’s, and your PHP error logs). Solution: Try dropping the time out down temporally to a lower value, to see if the sessions clear or not.
  • SEF If your site has a lot of visitors table jos_session can accumulate substantial overhead. And if you use default SEF, some 404 pages can make some bots to enter into loop, and those bots gives you a huge session overhead.
  • Site statistics from within Joomla. Enabling statistics through your site configuration just adds extra MySQL queries and increases server loads.
