I am using the payment form v. 1.4, but it stopped working not long ago. After entering information and submitting, I have the following message: 500 - Layout "blog" not found
Do you know what is happening? I am using Joomla 1.5.26.
I think you are using old version of the extension and It causes the error. In this case, please submit a support ticket sending us admin and FTP account of the site, send me the link to the form. I will check to see what's wrong and get it corrected for you.
