We just purchased the upgrade, removed our older version and installed the new one. It produces a "segmentation fault" for Apache and provides no other information in the error_log. The pages are just blank. The code is supposed to be compatible with php 4 and we are running php 4.4 We could not find any information on this on the forum or the knowledge base and already open a help desk ticket. However if anyone can offer any assistance here, it would be appreciated. Thanks in advance!
