Failure symptoms
After installing the plugin, error messages such as "An unexpected error has occurred" and "A database error occurred while reading an object" appear.
Cause
If the database used by formcycle is a MySQL or MariaDB, this problem may occur. Furthermore, the plugin itself is very large, e.g. the PDF Utils plugin 45 MB. This type of error occurs when the database does not allow such large blobs.
Solution
To solve the problem, increase the parameter max_allowed_packet, which is 16MB by default. For a permanent change, adjust the value within mysqld.cnf.
[mysqld] max_allowed_packet=128M
