Route 66 causing security problem on https website

 Hello, if I enable the 'System - Route 66' plugin (not the Page speed plugin) I get the following message when searching for a page on my website:-

"Secure Connection Failed

The connection to www.acupuncturetorbay.com was interrupted while the page was loading.

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the web site owners to inform them of this problem.

Is there a problem with the SSL certificate for the Plugin? or am I not setting up the Plugin correctly? any help would be gratefully accepted.

Thank you.

Hello Lefteris, I used Firefox and Chrome, neither worked and then I tried it on Safari and this didn't work either. Opera comes up with this
"This page isn’t working
www.acupuncturetorbay.com redirected you too many times.

ERR_TOO_MANY_REDIRECTS"

As soon as I disable "System - Route 66" The website is working again.

Thank you,

it worked! I was manily interested in speeding up my site so I will now test it. Thank you for all of your work.

Hello, here is some feedback. My Joomla version is 3.9.3 My PHP 7.2.13 When I 'Optimise CSS' I then lose the template of the website. So I am unable to go on and 'Minimise CSS'. I can optimise Javascript but Page Speed insights says that I should "reduce Javascript execution time" which is 3.5 seconds. My Speed rating has gone from 38 to 39 by doing all of this. One thing that lets me down is the embeded You Tube Player that takes 928 ms to execute. It also says "Minimise main thread work" which is 4.9 seconds. I will have to read far more in to this and find out how to get around it. My main rivals speed rating is 99 so I have a lot to do.
