Hi,
It seems that the problem that you have is most likely connected with some 3rd party plugin (or your site was improperly migrated / server misconfig) that automatically saves posts and pages. The url is not supposed to have:

Since you haven’t provided any access details to your site I can’t check anything else. But please try to go to the pages that containg peepso shortcodes and save them again, manually.
If that doesn’t help, please try disabling all of the plugins. All of them, PeepSo included, enable PeepSo only and see if that helps. Then switch on other plugins one by one and see when it fails.
If after all of that you still won’t be able to make it work I’ll need admin access to your site to be able to check what’s going on.
We can’t do anything else without getting access to your site and being able to inspect the problem.
Kindest regards,
Eric Tracz
