I upgraded successfully to 1.7.7.7. However, several issues are occurring. Errors occur that modules are not able to access directories. Ownership keeps changing from original owner "www-data" to "root". I reassigned ownership to "www-data" and tried to clear the cache. Some directories are created belonging to "www-data" and others "root". I have restored from backup, but still under 1.7.7.7. Can't go back to 1.7.7.6 without loss of data. Anyone experiencing this? Any Suggestions?
