Blank Screen for user management profiles on back end

Hello,

Just migrated from Joomla 2.5 to 3 and having lots of fun....

Joomla 3.4.4
CB 2.0.11
CB Subs 4.0.1

I'm having a ton of issues, so here is the first to handle. I'm getting a blank white screen when I try to view user profile under user management in the admin. Please help:)

Here is the error:
Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "/mnt/data/vhosts/casite-525491.cloudaccess.net/httpdocs/components/com_kunena/template/default/template.xml" in /mnt/data/vhosts/casite-525491.cloudaccess.net/httpdocs/libraries/kunena/template/template.php on line 142

Fatal error: Call to undefined method getconfirmemailTab::_addValidationJS() in /mnt/data/vhosts/casite-525491.cloudaccess.net/httpdocs/components/com_comprofiler/plugin/user/plug_cbconfirmemail/cb.confirmemail.php on line 68


Url for error:

Thanks in advance for the help!

I get the same error on the front end when logged in and try to edit profile:

Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "/mnt/data/vhosts/casite-525491.cloudaccess.net/httpdocs/components/com_kunena/template/default/template.xml" in /mnt/data/vhosts/casite-525491.cloudaccess.net/httpdocs/libraries/kunena/template/template.php on line 142

Also getting this related error? on top of kunena forum when logged in:
Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "/mnt/data/vhosts/casite-525491.cloudaccess.net/httpdocs/components/com_kunena/template/default/template.xml" in libraries/kunena/template/template.php on line 142

Any ideas how to fix and how related?

Thanks for the help!

Sorry for all the replies, but CB is pretty jacked up right now for me and I want to give and much info as possible about the error, I feel they are all inter related perhaps.

Please see screenshots of CB plugins that seem to be having issues... I installed all files when upgrading and doublechecked.

Thanks,
Mike

Your first issue is coming from Kunena so I can't help you with that and you'll need to post on their forums regarding it. Your second issue is due to out of date CB Reconfirm Email plugin. CB Privacy is also out of date and CB Captcha is officially replaced by CB AntiSpam. Please see the below chart and update your plugins as needed to latest nightlies.

Should I delete CB Captcha after installing anti spam then?
