Help Fix Slow website with errors

Hi.

I am a volunteer with a dog rescue and our Concrete5 website is very slow, both on the front and back ends. I am unable to update the add-ons or concrete5 version due to errors received when I try. Is anyone able to help me sort this out?

Hi Allison,

If Paul can’t help, please reach out: brian@mytooq.com. I’m in Edmonton and would donate my time to at least assess the issues (I’ve fostered with SCARS and adopted from PAWS out here).

Thanks,
Brian

There were some issues with marketplace integration. Updating to 8.5.12 and updating the integration configuration may clear up that part of the problem.
