Wordpress LScache Plugin: Issue plugin PDF Embedder
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi I installed the PDF Embedder plugin, it does not work with Minify JS and Combine JS in LiteSpeed ??Cache, error is caused: Setting up fake worker failed: Cannot load script at: https://domain.com/wp-content/litespeed/cssjs/7e923.worker.js” To try to solve this I disable Minify JS and Combine JS, then from GTmetrix / Waterfall Chart / JS I have 41 JS files, I removed the PDF Embedder plugin, purged the entire cache and again ran the test and still have 41 JS files running. My intention was to find out which JS file is using the PDF Embedder plugin to exclude it, but since I have the same 41 JS files after repeating the test again, I dont know which JS file is using the PDF Embedder plugin. If the PDF Embedder plugin is deleted, shouldnt the GTmetrix test have fewer JS files? How can i fix this? Right now the PDF Embedde plugin, Minify JS and Combine JS in LiteSpeed ??Cach? are active producing the error. Report Number: AETBVJYW The page I need help with: https://refrigeracionbarbosa.com/producto/valvula-de-expansion-ecualizador-interno-r22-r407c-tx2-068z3206-danfoss/ Hi, Please check this wiki You will need to repeatedly test it until figure out which one is actually causing it you can remove like half of the JS in the list each time , this will speed up things. best regrads, Hi I added all the JS one by one in the JS exclusion list, but it doesnt work, it keeps showing the error. When I test with GTmetrix the 40 JS files excluded appear. Please check to see what happens, here is the Report Number: TWGNPXLO Why if I excluded all JS files it doesnt work? When I disable Minify CSS and Combine CSS it works, although the issue occurs with Minified CSS Thanks Best Regards, Hi, Why if I excluded all JS files it doesnt work? make sure you have purge all after you make any change. now , please try put wp-content wp-include into excluding list, purge all , does it work ? Best regards, Hi Now if it works, but what happens, why adding these files if it works? What should I do? Best regards, Hi, Now , remove one of them , see which one works Best regards, HI When I add / wp-content it works, but without this it produces the error. I added just / wp-content without the rest of the JS and it works. What am I supposed to do now? Best regards, Hi, OK , now please try use following /wp-content/plugins /wp-content/themes if with these 2 it still works , repeat previous step , remove one of them , see if its plugins or themes caused issue. Best regards, Hi /wp-content/plugins caused issue. Now? Best regards Hi, Now use FTP or control panel file manager you should see some sub-directory inside of /wp-content/plugins , like /wp-content/plugins/litspeed-cache /wp-content/plugins/plugin-name1 /wp-content/plugins/plugin-name2 ... ... ... add them into the excluding list , then repeat the previous steps to narrow it down one quick check is add that PDF plugin into it first and see how it goes. Best regards, Hi With the PDF plugin it works. Should I leave it like that then? Best regards, Hi, You can leave with that if it contains a lot of JS , then you can further narrow it down if it only contains one or few JS , then it may not worth the trouble. Best regards, Hi Resolved Thanks Best regards, good to know
