Reload failed because retrieve_conf encountered an error: 255

Anyone know what this means and how to resolve it? Trying to do a new install of our phone system but have ran into this error.

exit: 255
Unable to continue. mkdir(): Invalid path in /var/www/html/admin/libraries/BMO/Media.class.php on line 34
#0 [internal function]: Whoops\Run->handleError(2, ‘mkdir(): Invali…’, ‘/var/www/html/a…’, 34, Array)

#4 /var/lib/asterisk/bin/retrieve_conf(78): FreePBX\Self_Helper->__get(‘Media’)
#5 {main}

I have the exact same error, and interested in the answer :slight_smile:
