WARNING: preg_match(): Unknown modifier '/' in /plugins/system/cache/cache.php on line 217

It's an error in Joomlas core caching extension. It's trying to call invalid REGEX. Looks like maybe due to using the "Exclude URLs" parameter in "System - Page Cache".

Thank you kindly, i had already determined it was something to do with the system-cache so i disabled that last night & it did seem to stop the errors thus far. However i didn't realize it was the excludes and that makes sense.
The reason for the exclude is our cb-login causes issues when we use dynamic caching. We'd like to use dynamic caching because it helps us slow down our account executions due to high traffic, however when we did use it we'd have people logging in as different users. So we tried to add the login page as an exclude. Unfortunately that didn't work.
Is there any way to use dynamic caching with cb? thank you again!

Page caching doesn't work well in dynamic environments. This is because Joomla caches the editor page buffer then simply outputs it again when called again. The result is always out of date data. It's really meant for blog sites. This is a problem for any page with a HTML form element since CB protects them all from spoofing and spam. Best way to exclude such pages is make a Joomla menu item to them then exclude that menu item in "System - Page Cache". Otherwise review the "Exclude URLs" parameter carefully to ensure you've supplied everything in the correct format.
