If you get a strange error message like this when you are making your marketstall listing
Fatal error: Call to undefined function convert_wysiwyg_html_to_bbcode() in /home/parentsp/public_html/community/forums/vblinklist.php on line 1931
Click back and continue editing your profile (that way you won't lose what you've already typed in). That error message means that you’ve put something in the wrong box or your description is too long. The most common mistake is to be put your web address in the banner field instead or the url field.
If in doubt, do everything except the banner – get the profile working and saved and then add the banner.
