Hi,
Are you running any other cacheing plugins or just Falcon?

Yep, i had another plugin that deals with caching. I just uninstalled it, and turned falcon engine off and back on.
Will see if it has this error in the future.
Do you think that tis was the problem?
Could be a good bet. It’s a good to only have one cache plugin active at a time.

Indeed, I’ve found caching to be one of the most tricky things in managing a website! At the least, only once cache plugin at a time! What is more, I’d suggest that Falcon might not be for everyone. It didn’t work for me and I’ve not risked turning it on since then, though I might give it another go once I have time to trouble shoot. MTN

Well, how about Falcon and a CDN like cloudflare?
Would there be an issue?

Hey guys.
Sorry to say after a few weeks with no problem. Today the hompage again switched to the Contacts page.
After clearing the FalconEngine cache it worked correctly!
Any thought?
Hi,
For your previous question, there aren’t any known issues using Falcon and CloudFlare together, and I have heard of other users with a similar setup. It’s possible if CloudFlare is set to cache HTML (which I don’t think is on by default), and if it strips any query strings from URLs, it might cause strange behavior when combined with Falcon.
There could be a conflict with some other plugin or the theme, if they handle query strings in an unusual way. For example, if you have page with ID #2, and go to domain.com/?p=2 if it loads the page instead of redirecting you to the post name like domain.com/contact/ then that might cause this issue.
(Wordfence automatically disables Falcon if it detects that permalinks have been set to the default option, uses “?p=” like that in URLs, but if a theme or plugin modifies how that works, it might be a possible cause.)
If the theme isn’t critical to your site, you could try switching themes for a while, to see if it still happens, but I know that isn’t always possible, especially if you need the site to look the way it does with the current theme.

Unforutantely changing the theme isn’t an option.
What else can be done?
Hi,
Since we haven’t seen this issue on other sites, it’s hard to say what might be the cause — one approach would be to wait until the wrong page appears again, and then check the file time of the cached home page (in wp-content/wfcache/), and look at the site’s access log to see what hit matches the same time. If there’s anything unusual about that visit, like a strange query string or path, it might help narrow down the cause. On most hosts, you can use the hosting control panel’s file manager or FTP to view the file modification times.
You could also manually check the contents of the cached file in wfcache — if there is another cache or other software causing conflicts or modifying requests, the file might show the right content, while viewing it on the site does not. If the host offers “Varnish”, you could try turning that off too — it shouldn’t cause issues like this, but if it’s misconfigured, it might be possible.
