Plugin Conflict With Flying Scripts by WP Speed Matters or W3 Total Cache

Hi there,

I am using your plugin, together with Flying Scripts by WP Speed Matters and W3 Total Cache and I have found when I have both your plugin and Flying Scripts by WP Speed Matters that it causes a conflict with Contact Form 7.

I really don’t know who the culprit is here Contact Forms 7, W3 Total Cache or Flying Scripts by WP Speed Matters.

When a user tries to email us via Contact Form 7, it throws an error “There was an error trying to send your message.” Every time.

When I disable just W3 Total Cache the error still occurs. When I disable just Flying Scripts by WP Speed Matters plugin the error still occurs.

Only when I disable both W3 Total Cache and Flying Scripts by WP Speed Matters is a user successfully able to send a message.

I’m not sure where to go from here, any help is appreciated.

I am going to cross-post this on W3 Total Cache and Flying Scripts by WP Speed Matters and will provide a link shortly.

WP 5.8.1 (Same results with 5.8)
Contact Form 7 5.4.2
W3 Total Cache 6.1.1
Flying Scripts by WP Speed Matters 1.2.2
