I was sure that ths is an error wich newer come back to me - was a relatively common one in early 2010-s, since dissappeared from my radar. 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.

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 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.

Joomla SEO Article Count: 21
How did you find this site? Did you asked yourself the question how a site can be found on the net? Watch your own habits, and you'll see: you are looking to the sites found on first page of the Google results for a given search term. Must be something very important, to go down to the second, and even to the third page. What else you use to find new web content? Social media? Recommendations from friends? Links on pages you like and visit? Do you know, that less, than 1% of existing web-pages are reaching the first page of the Google results for some search term? do you know, than less, than 17% of existing web-pages are even spidered regularly by the major search-engines? If you don't get spidered and/or you don't reach the magic first 3 pages for at least some search terms you are interested in - you aren't exist. And I can't believe, that anyone building a web-page plans to remain hidden... So, how you can get there? Enter the art of SEO. You will find some interesting, Joomla-specific ideas here which may help you learning it! And never forget: SEO is about what you do every day. SEO is a long term strategy - not a quick fix.
