Hello @sunsta,
Thank you for reaching out.
I fully examined the issue you described but was unable to replicate it on my end.
Also, WooCommerce store notice is working fine on my end in all version of PHP: https://postimg.cc/zybssf95.
Regarding the Critical Error, since you’re seeing a general “critical error” message. Please enable WordPress debug mode by following the steps here: https://ww.wp.xz.cn/documentation/article/debugging-in-wordpress/.
Once enabled, share the exact error message here as code (you can paste it or upload to Pastebin site or Gist site (GitHub). That will help us pinpoint what’s going wrong on your website.
To help us investigate further, please also provide:
1. When did you first notice the issue, after a specific update, on a particular device, etc.? and what are the exact steps that trigger it? Screenshots or a short video are very welcome (Loom, Postimages, Google Drive, Dropbox, etc).
2. Explain to us step by step how we can reproduce the issue so we can recreate it somewhere other than your website.
3. Your system environment info: go to WP Dashboard > Tools > Site Health > Info tab and click “Copy site info to clipboard”. Paste it here as code or share via https://pastebin.com or https://gist.github.com (you can remove your email from the content).
Before sending these, please make sure that:
Everything on your website is running the latest versions (WP, theme, plugins).
If possible, perform a basic troubleshooting checkup method and make sure the issue is related to our theme or plugin(s). To do this, deactivate all other plugins then activate them one by one and check for this issue. Continue doing this until you find what product is causing a conflict with our product. Then provide the details as explained above.
Note: If you have a caching plugin or server-level cache (CDN, browser cache, etc.), please clear it or disable it so your changes take effect properly.
Please keep us posted.
Thank you,
Best Regards
