On a newly installed FreePBX 15, I’m seeing a lot of various messages on console.
Among them many WARNING or ERROR as for instance:
WARNING[13421]: pbx.c:8732 ast_context_verify_includes: Context ‘macro-block-cf’ tries to include nonexistent context ‘macro-block-cf-custom’
Have you successfully removed all of them as this could help to quickly focus on real errors, if those ever happen ?
Those specific warnings, the ones that take the form " … tries to include nonexistent context …" can be stopped by disabling the ‘custom includes’ feature in Advanced Settings. I’m sure there will still be others you are stuck with.
