After changing hoster
 

Warning: Division by zero in ..gallery/pp-inc.php on line 1088

That suggests to me that your columns variable in your admin settings one of those is set to 0

Chuck, tell me where to look

I would suggest your admin layout options make sure no settings for columns or rows is set to 0 as they should never be set to 0. The error suggests that the columns is set to 0

Yes, indeed. But the old hosting with these parameters it worked.

Thanks!

I do not think it worked. Maybe your old host suppressed display of errors.

admin panel->Statistics

Fatal error: Maximum execution time of 30 seconds exceeded in adm-inc.php on line 700

You can place at the top of pp-inc.php under the error reporting line this line and it should help

There already have these lines

Go to Admin -> show phpinfo

what is there for max execution time?

I mean I know why it times out because it stats the data directory and really noadays 30 seconds for a script to execute is a bit low it should be higher.

I can say if you can not change your server you can try removing this line from adm-misc.php

Thanks

No problem glad to help
