I am using different categories of plans for various aspects of our site and thus been editing the emails and messages for each plan. All is good until I get to the Subscription Approved Body email, which triggers an error as follows:
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.
I'm not using a table, and am copying text from the User email body (that gets sent automatically when online payment is made and doesn't require subscription approval). I've checked the HTML code, all seems fine so I'm not sure if it is something I'm doing or an error in that particular text input area within the component.
I contacted my host who says there has been some security upgrade maintenance of the DBs and many sites have been experiencing problems and errors. I tried to look at the phpMyadmin, but it isn't accessible at the moment, so quite probably this server work is the cause, and I certainly hope that it will resolve by itself when they are done.
I'll let you know if I can't sort it out from this end.
