Tips & Tricks Joomla Troubleshooter
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!
Recently in more (usually cheap) hosts more of my clients reported a strange error, wich showed up recently, withouth notice.
The error message is like this:
1104 The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is okay
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?
OK, so, wasn't the best setup condition available, but usually this is not a dealbreaker.
And BUMM, I have seen an old "friend", a popup saying:
ERROR: Invalid login
... and does this randomly, both in frontend and backend, sometimes showing the correct pages, and rarely an error message saying, that "table '#__session' is marked as crashed and last (automatic?) repair failed".
After updating K2 to version 3.6.3, in the backend, when tried to edit one of items, I got this error:
Error decoding JSON data: Syntax error.
After upgrading to Joomla 3.6 I had a nasty surprise - in the Joomla Installer the tabs - Install from file, Install from folder etc.., all but the Install from Web - where all gone. Of course, nothing found on the web: this happens when you are an early adopter. But I discovered the "fix" accidentally, on my own.
If you search on Google for the term "joomla can't login after moving to new server" - or something similar, you will get more, than 1 million hits for most of the combinations.
So, you aren't alone. And there are plenty of suggestions, on what might gone wrong and how you might find that, and there are verious fixes. But what if you moved the site to another domain? From development server to it's final place? This is a subject wich is rarely touched by those advices.
