Hello Nicholas
I am actually having the same issue. First thank you for a great product, I've installed this on nearly 50 clients so far.
However this is the first time I am having this type of issue. Normally I would just edit and force the buttons but this specific client wishes to use the freepbx module to make changes in the future.
This install has http://fop2.com/file.php?file=20 installed and fopadmin 1.2.6
Asterisk version is Asterisk 1.4.22-4 (trixbox 2.6.2.3) - I havent had a chance to upgrade them as of yet in regards to asterisk etc..
Any ideas to help point me in the right direction here?
I installed in fop2 first then the freepbx module.
If I do not create groups and don't use the web interface (freepbx) the buttons show up just fine however if I DO use the freepbx interface to configure groups, the page shows up blank after logging in.
I thought this was an issue with mismatch version from fop2 and freepbx module - however I appear to be using what is directed.
Any assistance would be greatly appreciated.
Kind Regards
