Site loads randomly with problems

It sounds like you’ve done thorough troubleshooting. Given the intermittent nature of the issue, it might be worth checking your hosting server logs and reaching out to Namecheap support to rule out any server-related issues. Cloudflare settings could also be a factor, so double-check those too. It’s good that you’ve explored plugins and themes as potential causes. Keep digging, and hopefully, you’ll pinpoint the root cause soon. Good luck! ???

@danitatsan Thank you for your response!

I went to check the error logs on the server and found a recurring one related to the issue. The curious thing is that the error occurs even when the theme is not active. Do you know if the inactive themes could still influence something like this?

This is the error:

It’s interesting that you found the recurring error even when the theme is inactive. Inactive themes usually shouldn’t affect your site’s functionality. The error you provided points to an issue in the “enzy” theme’s code related to a call to the is_empty() function. It seems like this function is not properly handling a null value, which could potentially lead to the intermittent loading problems you’ve described.

Considering this, it might be a good idea to reach out to the theme’s support or development team to inquire about this specific error and whether it could cause the issues you’re facing. They might have insights on how to address this issue or if there’s a recent update that could resolve it.

Also, regarding the “Cron reschedule event error” and the “Undefined offset: 1” notices, it’s worth looking into the respective plugins mentioned in those errors to ensure they are up to date and properly configured.

Keep working closely with your theme’s support and reviewing your plugins to troubleshoot further. Hopefully, you’ll be able to resolve these issues soon. Good luck, and don’t hesitate to seek more assistance if needed! ???

And suddenly, without doing anything really significant, the problem stopped appearing. I didn’t update anything I didn’t do before, so it’s very likely that the problem was related to hosting or cloudflare, maybe with an old cache, it’s a rare case.

Anyway, I will try to contact the Theme support team to fix that error as well.

Thank you very much @danitatsan for your help and willingness.
