There are certain errors in the system which can be easily corrected by an administrator. Indication of such problems could be "Bad Server Response" errors while you visit the list or detail page for some entity or record. This errors can be corrected by rebuilding database and/or clearing the system cache.
Database Rebuild
AtroCore uses its own ORM system. It means that the database structure is first described as metadata with the help of JSON files. This metadata is synchronized than with the real database structure.
Sometimes, some system errors result in differences between the database structure and these metadata. To solve this kind of problems the feature Rebuild Database was implemented.
In this case, go to "Administration > Maintenance" and select Rebuild Database to actualize your database structure. You will be presented with a list of commands that will be executed on the database before confirming the operation. If this does not resolve the issue, contact support.
If database rebuild is required, the
Rebuild Databaseoption will also be shown in the User menu for admin users.
Clearing System Cache
Metadata and frontend are usually cached. In very seldom case it may results in errors. To solve these errors go to the Maintenance section in the Administration and click on the Function Clear System cache. To be sure you have no problems with the database structure click on Rebuild Database in the same section.
The
Clear System cacheoption is also available in the User menu for admin users.
