Hoping someone might be able to help, I have setup SME 9.x (Clean install) then fully updated after that I installed Horde 5.2 and all is working in webmail.
When I setup EM Client I can get the contacts, emails to work but calendars are not working - items created in EM disappear after syncing is completed.
The webmail calendar works and events are saved etc.
Checking the SME messages log I see
PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 30720 bytes) in /usr/share/pear/PEAR.php on line 336
PHP Fatal error: Class declarations may not be nested in /usr/share/pear/Horde/Support/Backtrace.php on line 12
have searched the form and googled but no luck
