Sorry for all this trouble with the Community Templates. Let’s Encrypt, our SSL certificate provider, made a change (DST Root CA X3 Expiration (September 2021) - Let’s Encrypt), which is the root cause for an SSL error while fetching the community templates. Unfortunately, after September 30th, some platforms don’t trust the Let’s Encrypt ISRG’s “ISRG Root X1” certificate, which causes this error.
We believe with time, this issue will be solved. Meanwhile, as mentioned by @timmse, the workaround is to install (and activate) the Bricks child theme (you can get a copy of it through your Bricks account page) and add the following code snippet to the functions.php file:
We were caught by surprise with this SSL issue and we immediately add an hotfix to the current Bricks version (1.3.4) to avoid issues in the license activation.
For the Community Templates, we proposed a workaround. A fix for this will also be included in the coming Bricks release (1.3.5).
