Website issues?

Is some sort of maintenance being done recently?  When I try to look at my profile (or others), I get the following error:

0 call_user_func_array(): Argument #1 ($callback) must be a valid callback, class Joomla\CMS\Cache\Cache does not have a method "call"

I'm also unable to add media to my reviews.  I am presented with a 500 server error.

 

Hi Kathy,

I did recently update much of the software on the server and had a few issues. I wasn't aware of these remaining.

Thanks I'll research them and get them fixed. It may take a few days. I caught COVID and am moving slower.
