I don’t know under what situation the `wp-content/db.php` file could be loaded without WordPress itself also having been loaded. * Previous thread: [https://wordpress.org/support/topic/php-error-435/](https://wordpress.org/support/topic/php-error-435/) * * Do you have any idea when this error appears? eg. does it appear when viewing a certain page or performing a certain action? * Can you provide a list of active plugins on your site? * Thread Starter [HKP](https://wordpress.org/support/users/hiskingdomprophecy/) * (@hiskingdomprophecy) * [5 years ago](https://wordpress.org/support/topic/line-140-issue/#post-14511899) * [@johnbillion](https://wordpress.org/support/users/johnbillion/) * Hi John, * As far as I recall this is the first time I have seen this error. * I forwarded it as it was a) lengthy (not the normal 1-line notice) and b) it related to a future version php warning. * As I recall, I had just deactivated your plugin which had been running for a few days, as I was not finding any useful information as to which script was causing our high cpu load and excessively high load-averages on the server. * We use Cache Enabler (CE) which was set to empty the cache when any plugin was activated or deactivated. This has been an issue for us, for if the Cache is full at say, >250Mb, then it often caused a critical error when a plugin was deactivated. * This is most likely what happened here. I deactivated Query Monitor with a full cache and it threw out that warning message. * FYI, I have now changed the CE settings so it does not empty the cache on a plugin activation or deactivation – as the plugins I turn on and off often are only for testing etc. and not post content related. * Actually, things work much better now that the CE cache remains active, and I am able to turn your plugin off and on without throwing an error message. I know because I just tested it here and now. * I hope this helps. * A list of our plugins is below. * Since you are aware of this, I will make this issue as resolved….. or at least known 🙂 * If you need more information, please do just ask. Pleased to help if I can. * Regards and thanks, Angus * ``` -- WordPress Active Plugins -- AddToAny Share Buttons: 1.7.44 Advanced Editor Tools (previously TinyMCE Advanced): 5.6.0 All in One SEO: 4.1.1.1 Better Search Replace: 1.3.4 Broken Link Checker: 1.11.15 Cache Enabler: 1.7.2 Classic Editor: 1.6 Cloudinary: 2.7.3 Extra Sentence Space: 1.3.9 Fast Velocity Minify: 3.2.2 GTranslate: 2.8.63 iThemes Security: 7.9.1 List category posts: 0.84.2 P3 (Plugin Performance Profiler): 1.5.4 Pre* Party Resource Hints: 1.7.6.3 Query Monitor: 3.7.1 RefTagger: 2.4.1 UpdraftPlus - Backup/Restore: 1.16.56 Weaver Xtreme Theme Support: 4.4.5 WPBruiser: 3.1.43 XML Sitemap & Google News: 5.2.7 -- WordPress Inactive Plugins -- Database Collation Fix: 1.2.7 Fast Secure Contact Form: 4.0.56 GTmetrix for WordPress: 0.4.4 Optimize Database after Deleting Revisions: 5.0.4 Redis Object Cache: 2.0.18 WordPress Importer: 0.7 WP Crontrol: 1.10.0 WP Memory: 2.10 WP Rollback: 1.7.1 ``` Viewing 2 replies - 1 through 2 (of 2 total) The topic ‘Line 140 Issue’ is closed to new replies. * ![](https://ps.w.org/query-monitor/assets/icon.svg?rev=2994095) * [Query Monitor](https://wordpress.org/plugins/query-monitor/) * [Frequently Asked Questions](https://wordpress.org/plugins/query-monitor/#faq) * [Support Threads](https://wordpress.org/support/plugin/query-monitor/) * [Active Topics](https://wordpress.org/support/plugin/query-monitor/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/query-monitor/unresolved/) * [Reviews](https://wordpress.org/support/plugin/query-monitor/reviews/) * 2 replies * 2 participants * Last reply from: [HKP](https://wordpress.org/support/users/hiskingdomprophecy/) * Last activity: [5 years ago](https://wordpress.org/support/topic/line-140-issue/#post-14511899) * Status: resolved
