I am testing phplist and tried to send campaign. In start campaign, I added html code in compose message It was broken especially these tags
<table> <div> <tr> <strike>
The test mail shows in the top "e>" and  , iv> r> and some "text" as "t ext" and then all images normally. Some
<a href> on <img> are also not working.
After lot of trying I sent one blank message which also had e> printed in email body.
Can anyone help me pointing out where this header part is? Why html is broken? Please help
I believe it's related to your PHP version, login to your host cpanel and try a different PHP version. (I.E. from 5.2 to 5.3)
