It shows me this error when confirm the purchase paying with paypal:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 120 bytes) in /public_html/jupgrade/libraries/joomla/language/language.php on line 792
and this with bank transfer:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 491520 bytes) in /public_html/jupgrade/libraries/tcpdf/tcpdf.php on line 11657
Anyone knows? I migrate virtuemart 1.1.9 to 2.0.24b and joomla 1.5 to 2.5
