Hi, I wanted to report a bug with the Embed Power BI Reports plugin that is causing a sitewide issues for us. The file /wp-content/plugins/embed-power-bi-reports/Wrappers/secureInput.php is producing output at line 344 before WordPress headers are sent. This triggers a “headers already sent” PHP warning and corrupts every AJAX response on the site, breaking the WordPress media library, Gravity Forms CSV exports, and plugin update responses among other things. Deactivating the plugin immediately resolves all issues. WordPress version: 6.9.4 Plugin version: 1.2.3 PHP version: 8.2 Happy to provide additional details if helpful. Thanks. Hello @engeniusweb , Thank you for reporting this and for sharing the detailed information. This was caused by a closing PHP tag in the plugin file was sending output before the WordPress headers, which led to the AJAX and media library problems you described. The fix has already been added and will be included in the next plugin release going out this week. We’ll let you know as soon as the updated version is live so you can update the plugin. We appreciate you taking the time to report this issue and helping us track it down quickly. Please feel free to reach out if you have any other questions. Regards Team miniOrange Hi @engeniusweb , The patch has been released. Please upgrade your plugin version and let us know if you still run into the issue. Thanks, miniOrange Thank you! It seems to be resolved!
