<b>WARNING:</b> strlen() expects parameter 1 to be string, array given in line 720 of file /home/mysite/public_html/amember/member.inc.php This error just began happening. There is no rhyme or reason for it. How do I know what variable is causing the problem. Which is "parameter 1" that we are supposed to be talking about? Unfortunately I can't make any changes in the admin back end as this error prevents saving. The field that seems to have an error (keeps showing up in red as not entered and is a required field) isn't a string. It's a checkbox.
