Add/Edit contact/lead/product blank form after upgrade 4.4.1

Hello,

I just upgraded from VTE 4.2 to 4.4.1. Now when trying to add/adit a contact, lead or product I got a blank area in the page instead of the fields for inserting/showing data.

What could it be? I'm running PHP 5.3.23 and it worked ok with VTE free 4.2.

Thank you, best regards.

Try to delete the content of the folders Smarty/templates_c, smartoptimizer/cache and than clean the cache of your browser.

Hello, thank you for the reply. I already tried this solution several times, but the error hasn't changed. Do you please have any forther suggestion? Thanks
