S2Member Pro – A Powerful Membership Plugin For Wordpress v260312

- (Framework) **Fix:** Prevent a PHP 8.1+ deprecation notice from appearing above the admin Users table in some cases. - (Framework) **Security:** Improved debug log sanitization. - (Framework) **Improvement:** PayPal Checkout credential test and OAuth failure log entries now include client_len_hash / secret_len_hash values (length_hash, e.g. 80_4d9a7c1b2e8f4a21) to help compare attempted credentials during troubleshooting without exposing raw values. - (Framework) **Enhancement:** Added a new _No-Cache Headers Behavior_ option under _General Options > Performance & Caching_, making no-cache behavior configurable from the admin UI. It includes: - `Always` mode, the legacy safe default that prevents caching site-wide in case user-conditional output appears. - `Selective` mode, which was previously available only through a filter and may improve caching for guests, but can miss some runtime no-cache triggers. - The new `Evaluative` beta mode, which evaluates the page with more runtime information and may allow more pages to be cached safely for guests. - An optional debug header to help troubleshoot no-cache behavior. - (Framework) **UI:** Clarified the Download Options text to explain that unique download limits are counted in the last X days (rolling window), reducing confusion about whether the limit resets on fixed calendar dates. - (Framework) **UI**: Improved the PayPal Checkout credentials test failure message. - (Framework) **UI:** Fixed the PayPal button encryption admin notice so that it shows only to administrators in the WP Admin area, not non-admin users.
