I have a plugin called 'virtual theme' which I downloaded from the plugin directory, and it works great but i noticed sometimes when there's a change it with other plugins it seems to stop working and shows a page not found. Going to the plugin page it still shows like its active. So what i have to do to make it work again is click on deactivate and then click activate so it could start working. I notice this happens more when I end up deactivating another plugin this one stops working. I also notice that it happens sometimes when making an option change, like bbpress for example, after making a change there, Virtual Theme' stops working. Does anybody knows why it does this.
It's a bit of a guessing game without error reports. Here are a few ways to collect info which will help you or others diagnose the cause:
Turn on WP-Debug:
WordPress WP DEBUG Codex page *Be careful if your site is live if you choose to use
WP-Debug (Better for Live Sites):
Add the following code to your themes functions.php file. It will only show the errors when adding
Reference and usage instructions: Stack Exchange admin Best Collection Snippet
Checks to see if your theme or plug-ins are using deprecated functions which can cause issues.
Enable Error Logging:
Replace your current code in
Once you decide on which to use and implement it you'll start collecting data that can help you diagnose your issue. If you need help deciphering the data post it here. Maybe I can help, or someone else can assist you.
