Hello everybody,
i'v installed VM e-Tickets for Joomla 2.5 and it seems to run quite good. We've sold some tickets and recognizede, that we can't see anymore "sold tickets" in the backend. Joomla shwos fatal error:

Allowed memory size of 67108864 bytes exhausted (tried to allocate 3 bytes) in /usr/www/users/camerau/eisenzeit/jupgrade/libraries/joomla/database/database/mysqli.php on line 498

Then I raised memory_limit of php to 96 MB. The error turned up again.

Allowed memory size of 100663296 bytes exhausted (tried to allocate 32 bytes) in /usr/www/users/camerau/eisenzeit/jupgrade/libraries/joomla/database/database/mysqli.php on line 498

What can we do?
Thank you for your support!

Regards,
Alex
