Wordpress LScache Plugin: Critical CSS issue, syntax error unknown word
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, Im trying to use CCSS from litespeed, but all the ccss file in QUIC.cloud I saw the same syntax error, / CssSyntaxError: /wp-content/plugins/tourmaster/tourmaster.css:1:91734: Unknown word / I try to locate the error and asked to author of the plugin, both of us can not find it, pls help. The page I need help with: https://localdmcs.com There are many errors with that file. You can test CSS with a linter, an online tool can be found here http://csslint.net/. Ask the plugin author to use a linter on their CSS. It would pick up the issues instantly. I recommend https://stylelint.io/ but they can also use https://github.com/CSSLint/csslint. Tell them to incorporate it into their build process before releasing updates to prevent issues in future. Here are the 3 critical errors. line: 1198, column: 105 Parsing Errors Expected RBRACE at line 1198, col 105. .tourmaster-tour-category-grid.tourmaster-with-thumbnail .tourmaster-tour-category-overlay opacity: 0 alpha(opacity=0) line: 1226, column: 107 Parsing Errors Expected RBRACE at line 1226, col 107. .tourmaster-tour-category-grid-2.tourmaster-with-thumbnail .tourmaster-tour-category-overlay opacity: 0 alpha(opacity=0) line: 1253, column: 107 Parsing Errors Expected RBRACE at line 1253, col 107. .tourmaster-tour-category-grid-3.tourmaster-with-thumbnail .tourmaster-tour-category-overlay opacity: 0 alpha(opacity=0) The issue is that alpha(opacity=0) is not valid CSS, it should be filter: alpha(opacity=0) . Hi, this means I should correct all the errors so that the critical css could work? Yes
