Wordpress LScache Plugin: 503 Service Unavailable Error after Updating.
Last Updated on: Wed, 15 Apr 2026 00:00:02 There is problem with the Latest Update. The plugin starts using a lot of Resources and after sometime, the site goes down with 503 Service Unavailable Error. So, I restored to PREVIOUS VERSION and the site (bccfalna.com) is running fine now. This topic was modified 4 years, 10 months ago by bccfalna. Can you give a report number? Also did you capture any PHP error in log? Report Number? I dont know anything about it. I didnt received any PHP Error in log. I updated the PLUGIN today around 1 PM (India) and after that around 5 hours my site was approximately DOWN with 503 Error. Then I restored the OLD VERSION, and my site is running fine now as before. After updating the plugin, the CPU Usage stuck at 100% in my cPanel. So, I am sure, there is some kind of issue in the latest version of the Plugin. > https://wordpress.org/support/topic/how-to-get-help/ This is how to get the report number.
