CustomContexts module

I’m having difficulty installing the module. I believe the module was installed once before, but it was either removed or a backup was restored and broke the install. I downloaded the most recent version of the module for FreePBX 2.5.2.6 and when I went to upload it, I saw that the module admin said Custom Contexts was not installed but locally available. I tried installing it, but the web GUI hung for ~5 minutes. We are running Elastix (1.6-13), and the Elastix GUI continued to work. Eventually the FreePBX web GUI came back. I tried removing the existing module installation package and uploaded the newer version - same problem.

Anyone have any thoughts about how to go about fixing this? I assume there’s a log file somewhere that would show what the install is hanging on.

Thanks for any help!
