Content Encoding Error occurred when visit Dashboard

I am using Concrete5 version 8.5.4 and PHP version 7.6.
Whenever I am trying to visit my Dashboard, then an error occurred:
“Content Encoding Error
An error occurred during a connection to
Please contact the website owners to inform them of this problem.
Try Again”
as well as sometimes when I logged in then the same problem also occurs.
One more thing, there’s no problem, when I trying to edit my webpages.
Finally I am unable to find out the way through which I can fix it.
Help me to figure out how to fix this issue.

If I’m not mistaken, you want to be on php 7.4. Give that a whirl and see if that alleviates your issues.

Hello @enlil
Sorry for mistake please, in previous my PHP version was 5.6 not 7.6
Now, I have changed it to PHP 7.4 and I will update you soon :+1:
Thanks and again extremely sorry for typos mistay.

Hi @enlil
My site works fine for PHP 5.6 and when I went to either PHP 7.0, 7.2 or 7.4 then it gives an error.
I have attached the screenshot of that.
Please review it.

Hello @enlil @TMDesigns

After a lot research and discussion, the solution is here:

Solution: This problem is related with “open_basedir” not with PHP and Cache folder.

In my hosting control panel> mydomain>files> open_basedir>disable

Done :white_check_mark:
