Have you tried alternate browsers? I have no trouble with P.com using Safari, but I know for some other forums and site “dashboards” I use I have had to switch to Chrome or they are glitchy,
This site was maintained for years with no income – I can’t blame the admins for having to include ads to pay the bills. Keeping forum and info sites like this on line is NOT free.
What is the problem you are having and what are you seeking to use the site for? If you are buying or selling paddling gear, your best best is your local Facebook Marketplace.
There are other paddling forums, like Song of the Paddle (which has mostly European membership) and there are regional canoeing and kayaking groups, also on Facebook, if you seek instruction and outings. Other forums, like QajaqUSA are for specific types of kayaking and require paid enrollment for participation.
But I’ve been on this forum for going on 16 years and have found it to be very informative and useful. Sorry you are having troubles but they are likely not insurmountable. Far as I know, the admins are unpaid volunteers – this is a free site so “customer service” is not a guaranteed right.
