One of server is hosting several domains with their wepages mostly in php. Server was running eayapache3 with php5.5. One of the domain asked to enable php5.6 recently. So we migrated the server from easyapache3 to easyapache4. Server hit full disk space today & apache stopped serving. Now we removed old backups to make space as a temporary measure. Now some domains are loading, and some are displaying http 500 error.
Please can someone guide us? FYI: I've restarted all relevant services, especially http & mysql.
