I have this issue when running the speed test in my website https://alumcenter.net
I have included a screen shoot.
I know the solution is to add a rule to the .htacces file
but I need to know the code to do it.
Pearl Themes answers:
Add the following code to your theme's 'functions.php' file.
That disables the canonical redirection.
Eff, I have try and did not work, any other options
Pearl Themes comments:
Kindly check your plugin conflicts once. Disable all the plugins and see if that fixes the issue. Then re-enable one plugin at a time to find the culprit plugin.
Let me know if you still have this issue. I am waiting for your response.
