Today one of my clients called me with this problem:
When I click article manager or category manager in order to edit an article or category, I see a page with no textarea, no buttons, no menus
Was a weird call, and proven to be a difficult problem

Did you ever get this annoying error?
Save failed with the following error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 SQL=INSERT INTO ***_contentitem_tag_map
After solving couple of times the "500 Internal Server Error" problem as described in a previous post, I received another complaint from one of my clients I host:
"I also cannot save the articles and here is the error I got 500 - An error has occurred!"
Easy cake - I was thinking, but after checking his account, discovered, that all settings described on that article (namely the collation settings in database) where correct.
I had been driven crazy recently by couple of my sites suddenly beginning to exhibit a very annoying behavior. Sites, which worked flawlessly over past months/years began to die when I tried to save something, from new or edited articles, modules, menu items, contacts.
Of course the first thing I done was to look to the error logs, then to enable debug and set the error reporting level to maximum. Nothing helpful.
Time-to-time I am hitting the wall with this, even with 100+ VM sites in my portfolio, and parts of VM core having my signature. Here are few tricks wich usually solves the problem.
It's annoying... your own Joomla site don't let you log in in the backend, and you see the above error message... What's happened?
Humm, there are couple of things you can do. Contrary of the lots of "smart" blog entries on the subject out there (last search revealed about 2 million hits) in most of the cases, regardless to Joomla version the cause is simple:
- JLIB_APPLICATION_ERROR_COMPONENT_NOT_LOADING reloaded
- The mail function has been temporarily disabled on this site
- reCaptcha stopped working
- JLIB_APPLICATION_ERROR_COMPONENT_NOT_LOADING
- Menu items keep reordering after migration
- Error: 500 - String could not be parsed as XML
- 1&1 SEF URL's problem reloaded
- Increase the available memory for your page
- MooTools problems after FireFox update to version 18
- Misterious "Bad Certificate" error when you click on certain inner links

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.
