Wordpress LScache Plugin: Image Pull fails So cannot Optimize images
Last Updated on: Wed, 15 Apr 2026 00:00:02 Image pull fails even on running wp-cron Error is: WordPress database error Unknown column root_id in where clause for query SELECT FROM wp_litespeed_img_optm WHERE root_id=0 I am running Version 2.9.9.2 Litespeed Webserver Cannot upgrade to 3.x.x as it causes failure of one captcha plugin. So have to be in V 2.9.2 How can this be fixed? The page I need help with: https://www.elearnings.dlife.in/ Hi, Did you upgrade to v3.0 and then reverted back to v2.9 ? What exactly issue you have with Cannot upgrade to 3.x.x as it causes failure of one captcha plugin. So have to be in V 2.9.2 ? Best regards, Yes on upgrade and then downgrade. I deleted the two lscache tables reinstalled the plugin and image opt works. WRT 3.x I use Match captcha commercial plugin. With 3.x captcha always shows exprired with all settings and excludes being same as 2.9.x I dont want to use the quic cdn. Math captcha Sorry for typo in prev reply. Hi, If you upgrade to v3 and then downgrade back to v2.9 , the database table is changed between v2 and v3 You may need to destroy all optimized images and re-start it. With 3.x captcha always shows exprired with all settings and excludes being same as 2.9.x may I know how did you configure it in v2.9 ? Best regards, may I know how did you configure it in v2.9 ? Just added the urls containing the math captcha inclusions to exclude urls So, for example: /contact-us/ /my-account/ /elogin/ /cart/ And this works fine with 2.9.x But fails with 3.x as it always throws error CAPTCHA expired. Hi, You mean exclude from cache ? or exclude from optimization ? if you try on v3 , do you have x-litespeed-cache: no-cache header ? Best regards, Exclude from cache the urls under Settings > Excludes > Do not cache URIs With 2.9 the no-cache header is present. Did not check with 3.x as was in hurry tk fix the issue since login was failing. But, the same set of URIs were there in exclude URIs. Still on every page with captcha same error Captcha Expired. I checked on dev install by upgrading from 2.9.x to 3.x, Purged all after checking all settings are fine and same as was in 2.9.x Cleared browser cookie And the error reproduces: ERROR: Captcha time expired. for all pages where the Math Captcha is displayed. The page does show the x-litespeed-cache: no-cache header So, not taking the risk with LIVE install now till this issue is fixed. Hi, If the image opt works fine on v2.9 , I will mark this topic as resolve , but please re-open it if it doesnt work. for math captcha issue , Is it possible you can set up a dev/staging site for this math captcha issue ? Best regards, If the image opt works fine on v2.9 , I will mark this topic as resolve , but please re-open it if it doesnt work.
