Symptoms

I get the following error when edit Sitebuilder modules eShop, Image Gallery, Guestbook, etc. in wizard.

Error! Operation has not been completed.

The same error is shown in Sitebuilder logs at Sitebuilder -> Logs.

What causes the problem and how do I resolve it?

Cause

The error may be caused by limits set in configuration of Apache module mod_security, PHP extension Suhosin or PHP configuration set in php.ini on server where the site is published to (publishing server).

Run script phpinfo on the publishing server to get list of modules, PHP extension and limits:

<?
phpinfo()
?>

Resolution

If the problem is caused by PHP extension Suhosin you may see the following error in log file /var/log/user.log on the publishing server:

Oct  6 6:44:56 hostname suhosin[11620]: ALERT - configured request variable value length limit exceeded - dropped variable 'request' (attacker '123.123.123.123', file '/PATH/TO/FILE')

If the problem is caused by mod_security look into Apache error log file for details.

Also verify that values of PHP variables memory_limit, upload_max_filesize and post_max_size are big enough. They are configured in PHP configuration file and should have at least the following values:

memory_limit = 32M
post_max_size = 24M
upload_max_filesize = 8M
