Three fucking hoorays! Bartlog was in dire straits after an update of a Drupal module, which put my site in off-line mode. Not only that, but I was completely unable to log in too. So I simply couldn't get in to fix the problem.
Now in such a case, there is only one address really: the Drupal.org site. It contains masses and masses of information. Completely unreadable too. Typically, you would search for a solution to your problem. Then you'd find a number of articles with promising titles, making you go 'phew' and increasing your hopes of salvation. Any such articel will begin with a perfect description of your problem, so you think 'Yes! Yes, that's me! That's exactly the problem I'm having!'
Unfortunately, the author who is generally a super tech geek then veers off and starts to discribe all kinds of obscure options and scenario's that you won't need, such as 'Indicentally, if you need to replicate this behaviour on the CERN quantum computer, all you need to do is...' When you've finished reading the article, you have a pounding headache, but you are none the wiser.
Anyway, maybe this experience will teach me to make back-ups more often (i.e. not every fourteen months or something).
