ThemeBot has been off-line for the past couple days. It seems that a combination of modules that were installed Wednesday caused some file or database corruption. I am still working on pinpointing what the problem was.
Fortunately, I had a full site backup from Monday morning. This archive has been successfully restored. However, a few posts from the forum were lost and anyone who signed up between Monday morning and Wednesday evening will have to re-register (the same username and password can be used).
I lost a few days of work and this causes a minor inconvenience for new visitors. All I can say is, make regular backups of both your files and databases for your website. Especially, make a full backup before installing new modules.
I have an automatic script setup that backs up all the mySQL databases for my sites on a daily, weekly and monthly basis. I will be writing a tutorial about how to set this up soon.
In closing, let me repeat... back it up! It can make the difference between what turns out to be a minor nuisance or a major catastrophe.
