Could not write into css file

Sorry for the inconvenience. Can you please attach the screenshot of the issue? I didn’t fully get the issue at the moment. Kindly help me to check the issue so that I can help you with it.

The plugin is still crawling through the pages, but several are already processed and failed. The page status is failed (failed tab in the admin panel). In the error column there is a “Copy Error” button, which when I click and paste, get the following output: “Could not write into css file”. This leads me to believe it’s some sort of permissions issue. Sorry, I’m not attaching a screenshot – currently unable to upload it. Will add later if necessary.

Thank you for sharing the info. Can you please check once is this due to any conflict? Please check once and let us know back the response? So that we will assist you accordingly to resolve your issue.

Hi,

I am facing the same issue. I have WP Fastest Cache & after installing this plugin & trying to generate critical css, every single one of th 36 pages has a STATUS of FAILED & the Copied eror message is “Could not write into css file”. So it is not working at all.

You say above to check if any conflict … but I dont understand what I can check?

Any advice?

Ok. Deactivating the Wp Fastest Cache plugin allowed the pages to be optimised, but it broke the site??? Didnt work at all.
