I keep getting recurring fatal errors on a couple of sites. Not fully sure what the plugin is conflicting with (if anything, or if it is just misbehaving). Here is the log report, with a full stack trace of what is happening. Can you help me troubleshoot this, or does this information point you in a direction that is useful? [24-Jul-2025 15:44:52 UTC] PHP Fatal error: Uncaught SQLite3Exception: Unable to execute statement: attempt to write a readonly database in /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-content/object-cache.php:2656 Stack trace: 0 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-content/object-cache.php(2656): SQLite3Stmt->execute() 1 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-content/object-cache.php(541): WP_Object_Cache->clear_flag() 2 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-content/object-cache.php(2685): WP_Object_Cache->__construct() 3 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-includes/load.php(893): wp_cache_init() 4 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-settings.php(147): wp_start_object_cache() 5 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-config.php(101): require_once(‘…’) 6 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-load.php(50): require_once(‘…’) 7 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-blog-header.php(13): require_once(‘…’) 8 /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/index.php(17): require(‘…’) 9 {main} thrown in /home/1398960.cloudwaysapps.com/bfqequvggj/public_html/wp-content/object-cache.php on line 2656 I should add that I’m experiencing these fatal errors on two vastly different websites, but both are hosted at Cloudways. Thanks for the defect report. I have seen this kind of error on sites where wp-cli jobs run under a different user than your web servers. What happens is this: the different user does an operation to sqlite. The operation creates one of the associated .sqlite files (.sqlite-shm or .sqlite-wal). That causes the ownership of the file to change. Then the web server comes in and it can’t use the file. So BOOM! Some other SQLite-based program (possibly the interactive sqlite3 shell program) runs and the same thing happens. If you’re on an Ubuntu / Debian os try doing sudo -u www-data wp whatever when you use wp-cli. Is this your problem? Please let me know.
