I tried to add a new Text Field to one of my tabs and got the following error.

moscomprofilerFields::store failed: CBSQLupgrader::changeColumn (ADD) of Table #__comprofiler Column cb_water failed with SQL error: Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs SQL=ALTER TABLE `jos_comprofiler`\n ADD `cb_water` varchar(255) DEFAULT NULL Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs SQL=ALTER TABLE `jos_comprofiler`\n ADD `cb_water` varchar(255) DEFAULT NULL

Any idea?
