Ok if you have a lot of fields, you will sooner meet a limitation of mysql in the column size.
So to solve this you have to limit the existing column size on mysql.
CB use a length of 255 characters for each column for a VARCHAR type, the most of time you don't need all this space, so we will reduce each one to a specific length.
Example:
For the firstname you have 255, you can reduce it to 100
For the middlename you have 255, you can reduce it to 100
For the lastname you have 255, you can reduce it to 100
And so one for each one fields
Be careful only does this for the VARCHAR type!!!
If you know how to use mysql it's quite simple:
1 - Save your database.
2 - Edit your database with phpmyadmin.
3 - Select "jos_comprofiler".
4 - Select all the fields “Check All” and click on the "change" button.
5 - Now reduce for each "Type" = VARCHAR, the "Length/Values" according to the length expect.
6 – Save.
6 - Install again the CB player Advanced.
7 - After you install you can do the same adjustment for the fields create by our plugin.
