Blog post is getting published after getting 500 error. It looks like cache purge for specific page is not working. Also new published blog post(after 500 error) is not showing because cache is not purged. * HTTP request: * POST mysite.tld/wp-admin/post.php?post=x&action=edit&meta-box-loader=1&meta-box- loader-nonce=xxxx&_locale=user * Response: {“code”:”internal_server_error”,”message”:”There has been a critical error on this website.<\/p>Learn more about troubleshooting WordPress.<\/a><\/ p>”,”data”:{“status”:500},”additional_errors”:[]} * Following things are noted: 1. no other page caching plugin installed neither server-level page caching system installed 2. no page rules 3. not using official Cloudflare plugin Viewing 5 replies - 1 through 5 (of 5 total) * Thread Starter [7887word7887](https://wordpress.org/support/users/7887word7887/) * (@7887word7887) * [3 years ago](https://wordpress.org/support/topic/error-while-publishing-updating-posts/#post-16767913) * Hi, * Also getting 500 response when clicked on Test cache * POST mysite.tld/wp-admin/admin-ajax.php action=swcfpc_test_page_cache&security =xxxxResponse headers: * Alt-Svc: h3=”:443″; ma=86400, h3-29=”:443″; ma=86400 Cache-Control: no-store, no-cache, must-revalidate, max-age=0Cf-Cache-Status:DYNAMICDate: Thu, 25 May 2023 11:58:11 GMTExpires: Thu, 25 May 2023 11:58:11 GMTX-Wp-Cf-Super-Cache: no- cacheX-Wp-Cf-Super-Cache-Cache-Control: no-store, no-cache, must-revalidate, max-age=0 * Response code: 500 Response body: empty * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [3 years ago](https://wordpress.org/support/topic/error-while-publishing-updating-posts/#post-16770862) * Hi [@7887word7887](https://wordpress.org/support/users/7887word7887/), Error 500, generally means Fatal Error which is happening when you are doing the ajax requests.

The `error_log()` is a native PHP function: [https://www.php.net/manual/en/function.error-log.php](https://www.php.net/manual/en/function.error-log.php)– how can it be an undefined function? Please check if this function is disabled in your PHP setup. * Thread Starter [7887word7887](https://wordpress.org/support/users/7887word7887/) * (@7887word7887) * [3 years ago](https://wordpress.org/support/topic/error-while-publishing-updating-posts/#post-16772300) * Hi [@isaumya](https://wordpress.org/support/users/isaumya/) , * My bad, error_log was disabled by admin. Now error_log removed from the function disable list and working like pro. * Thanks for the prompt response.
