HELP
Unable to locate the FreePBX BMO Class 'Userman’A required module might be disabled or uninstalled. Recommended steps (run from the CLI): 1) fwconsole ma install userman 2) fwconsole ma enable userman
I followed the steps but i still get the same error.
If I am not mistaken, you seem have same problem describe here : Sangoma Documentation or this one : Error during upgrade to freePBX 13 [SOLVED]
Please try that. It might help you or give you an idea
Also, you can provide what version are you using as well as logs or screenshot might be helpful so we can assist you 
If the above doesn’t help, open a PBXact support ticket and we can take a look at this for you. http://www.freepbx.org/support-and-professional-services
Really thanks but I was in a hurry, I redesigned the system and recovered the backup it’s all back online in a few hours, thank you anyway
