The most likely reason for your RSS feeds to show error is poor formatting.
This poor formatting can be caused by a blank space after closing php tag in a plugin or in your theme’s file.
The RSS error message will look something like this: Warning: Cannot modify header information – headers already sent by (output started at /home/username/example.com/wp-content/themes/twentysixteen/functions.php:433) in /home/username/example.com/wp-includes/on line 1228 If you are using Feed Burner, then your errors may look different.
Having said that, let’s take a look at what causes these RSS feed errors and how to fix them.
Earlier this week our friends at Meet Me On Board asked us to look into an issue where their RSS feed was not working properly.
When you tried to reach their feed you would receive the following message: “XML Parsing Error: XML or text declaration not at start of entity” For us the issue was blank space at the end of our file.
I may have deleted a tranistent feed table using the Clean Options Word Press plugin.
Are you encountering a RSS feed error on your Word Press site?
I’ll bet it has a lot to do with that caching plugin. I have left cache to 0 because if theres no cache data then it shouldnt take long to clear and show updated content.
Since having the plugin installed when I add new posts, they dont show.
1) By default, the UPDATE STATISTICS statement updates both index and column statistics.
Using the COLUMNS option of this statement will update column statistics only.
