A blank page (with header and footer) or a totally white screen?
Please provide a link to a page on your site where we can see this. Thanks.
A white screen, just like some error in functions file(although I’ve tried to remove every hook aswell with no result).
Site is tauruscrane.ru and problematic category is here http://tauruscrane.ru/feedback
Errors like this are logged. Check the error log on your server. If you can’t find the log, please contact your host.
Meantime, enable wp_debug and wp_debug_log and after an error, look at wp-content/debug.log to see if anything gets logged there. https://codex.ww.wp.xz.cn/Debugging_in_WordPress
You can also try this: Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
Server logs stable repeats single error, although I’ve tried to disable this plugin(Mailpoet) but error remained WordPress database error Table 'dbname.wp_wysija_subscriber_ips' doesn't exist for query SHOW FULL COLUMNS FROMwp_wysija_subscriber_ipsmade by require('wp-blog-header.php'), require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), do_action('init'), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, WYSIJA_control_front_subscribers->save, WYSIJA_help_user->storeSubscriberIP
For some reason, with set on true wp_debug wp_debug_log wp_debug_display nothing is being written in WordPress logs.
I recommend asking at https://ww.wp.xz.cn/support/plugin/mailpoet#new-post so the plugin’s / theme’s developers and support community can help you with this.
Plugin wasn’t that important so I deleted it and error no longer persists although category still blank. I checked logs with wp_debug it doesn’t record anything in that category… And server logs empty about that
Changed slug again and it worked. Curiosity of /feedback remain as blank page.
