You can view the source code to see the parsed content in the HTML format. This shows that the WordPress Feed output is correct. the problem lies in the format of a file. However, it is difficult to find out which file has a problem. The solutions provided on the Internet are roughly as follows:

1. check the wp-config.php file and check whether the code except the PHP subject has a carriage return character;

2, the same as above, detection of wp-rss2.php, wp-atom.php files, if not recently modified, can be skipped;

3. check the functions. php file;

4. Note that the feed is cached. after the modification is complete, send an article to re-create the feed for the WP program to view the effect;

5. if there are still errors, you can temporarily disable all plug-ins, change themes, and eliminate them one by one.
