Hi admin

"1118 Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs SQL=ALTER TABLE #__jsn_users ADD `lvdt_micro_3` VARCHAR(255)"

Hi,
I think you have reached MySQL hard limit, try to read here for more info: https://www.easy-profile.com/support/mysql-issue-that-no-one-i-know-has-ever-uncounted.html#reply-4666

Also, you can try to remove trashed fields.

You need to change column length from table "#__jsn_users", with some tools like phpMyAdmin.

We recommend to change only length of field where you know maximum length of values.

For example
You have a radio field with these options:
0|No
1|Yes

so value can be 0 or 1, then you can change column length from 255 to 1 (because you need only 1 char).

NOTE: we recommend to make a backup before change DB structure.

NOTE 2: the best way remain to convert the table engine from MyIsam to InnoDB (now InnoDB is used is all clean Easy Profile installations). To do this you can find many How To in the network ;)

Hi,
I don't know why, anyway this is a DB limit. Probably there is some DB configuration to solve this. I'm sorry but this is a DB issue.
