We’ll review the reported warnings with WordPress 6.9.4, PHP 8.2, and PPWP 1.9.18 and get back to you once we have an update. * We appreciate your patience. * Plugin Support [Quinnie](https://wordpress.org/support/users/quinniewpfolio/) * (@quinniewpfolio) * [1 week, 2 days ago](https://wordpress.org/support/topic/errors-from-plugin-5/#post-18925008) * Hi [@ftijay](https://wordpress.org/support/users/ftijay/), * We’ve created a staging site with WordPress 6.9.4, PHP 8.2, and PPWP 1.9.18, but we couldn’t reproduce the issue on our end. * Could you please share a screenshot or screencast showing where the issue occurs? * Also, could you try uninstalling PPWP Free, reinstalling it, and then checking whether the issue persists? * Looking forward to hearing back from you. * Thread Starter [ftijay](https://wordpress.org/support/users/ftijay/) * (@ftijay) * [1 week, 1 day ago](https://wordpress.org/support/topic/errors-from-plugin-5/#post-18925641) * After entering the password and submitting, thos comes up: * ![](https://wordpress.org/527b1461-fbbf-480c-a2a8-449e052670d6) * I tried deleting and re-installing. * Thread Starter [ftijay](https://wordpress.org/support/users/ftijay/) * (@ftijay) * [1 week, 1 day ago](https://wordpress.org/support/topic/errors-from-plugin-5/#post-18925642) * ![](https://wordpress.org/d858c29d-740b-40cb-8cb7-80ab1a002669) * Errors are the same as the first post in this thread. * Plugin Support [Quinnie](https://wordpress.org/support/users/quinniewpfolio/) * (@quinniewpfolio) * [1 week, 1 day ago](https://wordpress.org/support/topic/errors-from-plugin-5/#post-18926060) * Hi [@ftijay](https://wordpress.org/support/users/ftijay/), * Thank you for your help. I can see the issue now. However, the issue does not occur on our staging site, which suggests that it is related to something specific to your website. * I tried bypassing the cache by adding a random parameter to the end of the page URL, and the issue did not occur. Based on this, I assume the issue may be cache related. * You can try this link on your end and let us know: [https://www.friendsoftreasureisland.org/fti-board/?=clearcache](https://www.friendsoftreasureisland.org/fti-board/?=clearcache) * Could you please clear the server level cache and exclude the protected page from being cached? After that, please check whether the issue persists. * Thank you.
