Hi. This morning I have verified that ispconfig was not executing the websites backup, after I have tried to verify an upgrade with the following error. ispconfig_update.sh PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/apc.so' - /usr/lib/php5/20090626/apc.so: cannot open shared object file: No such file or directory in Unknown on line 0 PHP Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 523800 bytes) in Unknown on line 0 Could not startup. What I can do to easly restore the normal working? Thnaks.
