I'm helping on a site that is on a different server than usual and see this error regularly in the back end when trying to complete various tasks (e.g. clear caches, run database updates, etc.)
[debug_info] => TRUNCATE TABLE civicrm_menu [nativecode=1118 ** Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline.]
The site is mostly working, but as mentioned many tasks error out and the above shows in the debug log. What could cause this?
