Wordpress LScache Plugin: Site crashes after enabling Woocommerce
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello First of all, plugin options looks suberb, however I had no chance to test it as my site crashes after enabling Woocommerce ? it serves a blank screen with no data. When I enable Disable all features then its fine. When I deactivate plugin then its fine. When I disable literally all functions manually but keep Disable all features disabled it crashes the site. Any chances someone can help? BTW. admin works fine all the time. Here are some logs: 05/15/19 12:18:36.487 [188.123.220.116:58112 1 gIM] Accept Encoding: gzip, deflate 05/15/19 12:18:36.487 [188.123.220.116:58112 1 gIM] Cookie _lscache_vary: admin_bar:1 logged-in:1 role:99 05/15/19 12:18:36.487 [188.123.220.116:58112 1 gIM] X-LSCACHE: true 05/15/19 12:18:37.194 [188.123.220.116:58112 1 gIM] Media init 05/15/19 12:18:37.202 [188.123.220.116:58112 1 gIM] [Ctrl] X Cache_control -> no Cache ( logged in user ) => LSC_Control::set_nocache()@317 => LSC_Vary->__construct()@45 => LSC_Vary::get_instance()@639 05/15/19 12:18:37.204 [188.123.220.116:58112 1 gIM] CDN init 05/15/19 12:18:37.204 [188.123.220.116:58112 1 gIM] [Router] CDN bypassed: ajax call from admin 05/15/19 12:18:37.206 [188.123.220.116:58112 1 gIM] Task init 05/15/19 12:18:37.208 [188.123.220.116:58112 1 gIM] [Router] LSCWP_CTRL bypassed empty 05/15/19 12:18:37.582 [188.123.220.116:58112 1 gIM] [Ctrl] X Cache_control -> no Cache ( Admin page ) => LSC_Control::set_nocache()@317 => LSC_Admin->admin_init()@134 => /var/www/vvsimportoren/wp-includes/class-wp-hook.php 05/15/19 12:18:37.585 [188.123.220.116:58112 1 gIM] [Core] CHK html bypass: miss footer const 05/15/19 12:18:37.585 [188.123.220.116:58112 1 gIM] [Ctrl] not cacheable before ctrl finalize 05/15/19 12:18:37.585 [188.123.220.116:58112 1 gIM] [Router] get_uid: 3 => LSC_Router::get_uid()@203 => LSC_Vary->finalize_default_vary()@350 => LSC_Vary->_update_default_vary()@309 => LSC_Vary->_finalize()@501 05/15/19 12:18:37.585 [188.123.220.116:58112 1 gIM] [Router] get_role: administrator 05/15/19 12:18:37.585 [188.123.220.116:58112 1 gIM] [Cfg] role in vary_group [group] 99 05/15/19 12:18:37.586 [188.123.220.116:58112 1 gIM] [Vary] show_admin_bar_front: true 05/15/19 12:18:37.586 [188.123.220.116:58112 1 gIM] [Vary] admin bar : true 05/15/19 12:18:37.586 [188.123.220.116:58112 1 gIM] [Vary] no custimzed vary 05/15/19 12:18:37.586 [188.123.220.116:58112 1 gIM] [Core] Silence Comment due to REST/AJAX 05/15/19 12:18:37.586 [188.123.220.116:58112 1 gIM] X-LiteSpeed-Cache-Control: no-cache 05/15/19 12:18:37.587 [188.123.220.116:58112 1 gIM] [Core] CHK html bypass: miss footer const 05/15/19 12:18:37.587 [188.123.220.116:58112 1 gIM] [Media] bypass: Not frontend HTML type 05/15/19 12:18:37.587 [188.123.220.116:58112 1 gIM] GUI bypassed by no counter 05/15/19 12:18:37.587 [188.123.220.116:58112 1 gIM] [Optm] bypass: Not frontend HTML type 05/15/19 12:18:37.587 [188.123.220.116:58112 1 gIM] CDN bypass 05/15/19 12:18:37.588 [188.123.220.116:58112 1 gIM] End response ??????????????????????????? 05/15/19 12:18:37.617 [213.188.152.162:38082 1 BfT] ??POST HTTP/1.1 /wp-cron.php 05/15/19 12:18:37.617 [213.188.152.162:38082 1 BfT] Query String: doing_wp_cron=1557922717.4393310546875000000000 05/15/19 12:18:37.617 [213.188.152.162:38082 1 BfT] User Agent: WordPress/5.0.4 http://213.188.152.162 05/15/19 12:18:37.617 [213.188.152.162:38082 1 BfT] Accept: 05/15/19 12:18:37.617 [213.188.152.162:38082 1 BfT] Accept Encoding: deflate q=1.0, compress q=0.5, gzip q=0.5 05/15/19 12:18:37.617 [213.188.152.162:38082 1 BfT] X-LSCACHE: true 05/15/19 12:18:37.865 [213.188.152.162:38082 1 BfT] Media init 05/15/19 12:18:37.865 [213.188.152.162:38082 1 BfT] [Router] get_uid: 0 => LSC_Router::get_uid()@203 => LSC_Router::get_role()@222 => LSC_Config->in_exclude_optimization_roles()@351 => LSC_Media->can_media()@96 05/15/19 12:18:37.865 [213.188.152.162:38082 1 BfT] [Router] get_role: 05/15/19 12:18:37.866 [213.188.152.162:38082 1 BfT] [Router] role: guest 05/15/19 12:18:37.871 [213.188.152.162:38082 1 BfT] CDN init 05/15/19 12:18:37.872 [213.188.152.162:38082 1 BfT] Task init 05/15/19 12:18:37.873 [213.188.152.162:38082 1 BfT] [Router] LSCWP_CTRL bypassed empty 05/15/19 12:18:37.874 [213.188.152.162:38082 1 BfT] GUI init 05/15/19 12:18:38.229 [213.188.152.162:38082 1 BfT] [Core] CHK html bypass: miss footer const 05/15/19 12:18:38.230 [213.188.152.162:38082 1 BfT] [Ctrl] not cacheable before ctrl finalize 05/15/19 12:18:38.230 [213.188.152.162:38082 1 BfT] [Vary] role id: failed, guest 05/15/19 12:18:38.230 [213.188.152.162:38082 1 BfT] [Vary] no custimzed vary 05/15/19 12:18:38.231 [213.188.152.162:38082 1 BfT] X-LiteSpeed-Cache-Control: no-cache 05/15/19 12:18:38.233 [213.188.152.162:38082 1 BfT] [Core] CHK html bypass: miss footer const 05/15/19 12:18:38.233 [213.188.152.162:38082 1 BfT] [Media] bypass: Not frontend HTML type 05/15/19 12:18:38.233 [213.188.152.162:38082 1 BfT] GUI bypassed by no counter 05/15/19 12:18:38.233 [213.188.152.162:38082 1 BfT] [Optm] bypass: Not frontend HTML type 05/15/19 12:18:38.233 [213.188.152.162:38082 1 BfT] CDN bypass 05/15/19 12:18:38.233 [213.188.152.162:38082 1 BfT] End response ???????????????????????????
