I have 2 test events added:
http://inspired-ece.co.nz/events

If I select the 2nd event, It cannot be registed.

It appears a ticket price > $99 causes the failure?

Is there a work around or is this a limit for Decaf?

Thanks
Rhys

Hi Rhys, that may be a security filter on the site. Could you ask your host to adjust the mod security to allow use of base64?

Here is an example:

That is used by the ticket selector in Event Espresso 4.

Thanks Lorenzo for the prompt reply.
Looking in the logs I can see:

I have added to /httpdocs/.htaccess:

<IfModule mod_security.c>
SecRuleRemoveById 212010
SecFilterEngine Off 
SecFilterScanPOST Off
</IfModule>

However I still get the error and the log entry above.

Any other suggestions?

Hi, you may need to contact the host to have them set it up. That was an example from a different web host. However, all web hosts do not use the same systems.

Thanks – indeed I did need to ask the hosting company”

“The change is made in the vhost.conf file in the conf dir. This is something you do not have access to. The next version of plesk which we plan on upgrading our servers to in the near future, has an option in the control panel to disable mod-security rules.”

Thanks for your help.
