Hello @Methen

First off, back your database up and then check off option 'Take site down for temporary maintenance' under 'Admin' → 'General' page.

After that, run the following SQL query to increase the number the characters allowed for the 'title' field of table 'qa_userprofile' to, for example, 50 characters.

ALTER TABLE `qa_userprofile`
CHANGE `title` `title` VARCHAR(50) NOT NULL;

Also update file 'qa-config.php' by adding this line of code


which overrides the default value of 40

Finally, take your site up.


Administrators can add additional fields to user's profile. The following animation shows the error message the OP is referring to and also depicts how to add a profile field named 'Twitter' for letting users enter their Twitter user handle and how to fill it.

Wait a minute, how do you validate it?

Well, I will leave it as an exercise to the reader Grinning Face with Smiling Eyes People is already yelling at me because my answers are too lengthy anyway. But I can't help but give you a little hint: filter_profile.

But don't fret, here is how to delete it:

How to delete a custom profile field

There are tree types of fields:

  1. Single line of text: for small pieces of information, like field 'Full name'
  2. Multiple lines of text: Which allows users to press 'Enter' key to spread text into several lines; for example, the 'About' field
  3. Linked URL: Like single line of text but will turn the entered URL into a link; the 'Website' field is an example of this type of field

In addition, profile fields have two parts:

  • Field name: A short description of the content of the field. It is set once in the 'Users' administrator page. By default it can be 40 characters long
  • Field content:  It is filled for each user; allowing up to 8,000 characters

The following picture shows the form elements used for these type of profile fields. Note red numbers were added, these numbers identify the type of field in use (see above):
