XYZ Contact Form Manager 1.2
Theme - CyberChimps iFeature Pro
Plugin - vSlider 4.1.1
As part of the above site build, we had XYZ Contact Form Manager 1.1 installed and running correctly. I ran the automatic upgrade for XYZ CFM 1.2 today and immediately started received half a dozen php error at the top of the screen, in both admin and public site. These pointed at undefined pages in the vSlider plugin.
Only the XYZ CFM was upgraded to 1.2 (from 1.1) and nothing else had been changed on the site. Disabling the XYZ CFM 1.2 removed the errors. Using FTP to replace the XYZ CFM files back to 1.1 and reactivating the plugin did not regenerate the php errors.
There is a conflict between XYZ Contact Form Manager v1.2 and the vSlider v4.1.1 plugin, that has been introduced in v1.2 of XYZ CFM.
As the vSlider is a part of the paid-for iFeature Pro theme, we have had to disable and roll back the XYZ CFM to v1.1
I am considering changing to Secure and Simple Contact Forms if the faults introduced in CFM 1.2 cannot be quickly rectified.
