who's online error (bug?)

I am getting this error message when coming back from my payment gateway:

1406 Data too long for column 'last_page_url' at row 1
in:
[insert into fmwhos_online (customer_id, full_name, session_id, ip_address, time_entry, time_last_click, last_page_url, host_address, user_agent)

I have tried to change the field to text in the MYSQL database but it will not let me. I get error 1170

Is this a bug and is there a fix?

Thanks

You cannot change it to TEXT as there is an index on the field ...

You can try removing the index for the last_page_url then try a TEXT field type to see what is triggering this error ...

Any idea what the URL is that is being attempted to be added to the whos_online table that is so long?
