Проблемы с th_mailformplus
 

Не могу проинсталлировать это расширение. Точнее проинсталлировалась с ошибками, а при создании контента выдаёт такую ошибку:

2: SQL error: 'Table 'db_asfo.tx_thmailformplus_main' doesn't exist' (tx_thmailformplus_main:NEW41ebd2e61cc3b)

Как это вылечить?

I am not sure but may be at installation that table was not created so you have this message. I had similar problem on windows with mysql 4.1 or something. The problem was the extention's sql file have statement was wrong. Actually it was good for old db version but not 4.1. If I recall correctly it was something about default value (default = 0). The workaround is to change the sql then create table then all supposed to be well.
