This Message I get at the Update to 0.5.4 (MySQL: 4.0.21)
The error was: SQLSTATE[42000]: Syntax error or access violation: 1170 BLOB/TEXT column 'name' used in key specification without a key length
It is necessary that the “name” is part of the Index?
If not, we can delete it as Index and all is fine style_emoticons/<#EMO_DIR#>/smile.gif
