[SOLVED] canvas and avatar: gender?

I used it like that:

[cb:if canvas!~"/(nophoto_n|tnnophoto_n)\.png$/"]Show if there is a Canvas[/cb:if]
[cb:if canvas~"/(nophoto_n|tnnophoto_n)\.png$/"]Show if there is not a Canvas[/cb:if]

I tried a lot now.
It seems to be as follows:
REGEX in the Layouts (like Profile Value Layout...) leads to the "forbidden" window.
REGEX in CB_conditional works fine!

is this a host problem or a programming problem in cb?
EDIT:

when I use REGEX in the global description of a custom HTML field, it works without problems.

Seams to be working perfectly fine in layouts using your above regex. You'll need to debug the error further to see what is actually happening. Enable debug mode and maximum error reporting in Joomla global configuration. Next see if any fatal errors are output. If none check server error logs to see if any errors are present. If none contact your host as it could be mod_security.

Yes it was the mod_security. Now it works.

if I create a new field with the same settings like avatar and place it on the same place,
the image is not"circle bordered"

The "Style" parameter for your image field isn't working? Does it work in a position other than canvas profile image? Seams to be working fine in my tests. When substituting the field in you need to be sure to substitute in the HTML formatted value using the below usage.

[cb:userfield field="FIELD_NAME" /]
