I tried to update the tables of the version 1.2.8 B4 using one backup that I had made of tables created by version 1.2.7, but not had success in some items.
The table with the BOT's address and the table of blocked IP addresses were not updated correctly... some idea of what might be happening?
Would not you create in JoomlaWatch a way to save the tables, if they exist? A function to verify the existence of old tables, and not establish if they found out that they already exist? I think it would facilitate the process of updating much of versions in JoomlaWatch.
