Compatibility issue with W3TC

Hello,

I just installed Optimole on my WordPress. I have a message in the tab “Problem issues”: “It seems your are using W3 Total Cache. If you are using the CSS or JavaScript minify/combine option from W3 Total Cache -> Performance -> Minify page add this line: https://mlujvrffmpvv.i.optimole.com/* to Include external files/libraries and check Use regular expressions for file matching checkbox.”

I have done so. However, the message is still there. Is it normal? Also, I’m working on a sub-domain at the moment, in http (not https) until my site is ready, then I’ll transfer it to my main domain (in https). Therefore, should the line be https://mlujvrffmpvv.i.optimole.com/* (without the “s”)? I also tried both (http and https), but the message is still showing : “It seems your are using W3 Total Cache. If you are using the CSS or JavaScript minify/combine option from W3 Total Cache -> Performance -> Minify page add this line: https://mlujvrffmpvv.i.optimole.com/* to Include external files/libraries and check Use regular expressions for file matching checkbox.”

Please let me know if I should use http or https, and please let me know if it is normal that the message is still showing?

I look forward to receiving your answer.

Kind regards,

Laurent
