XML Parsing Error

Reported by: ingstra Owned by:
Milestone: Priority: normal
Severity: normal Version: 4.4.2
Component: General Keywords:
Focuses: Cc:


I don't remember which version it started at, but after this one upgrade, when trying to run upgrade.php, I got the error message

XML Parsing Error: undefined entity Location: https://www.ftek.se/main/wp-admin/

<title>WordPress &rsaquo; Uppdatera</title>"

I also get errors for &lsaquo.

For some reason the error disappeared when I removed the "xmlns" in <html xmlns="http://www.w3.org/1999/xhtml"> in the source code. But now when trying to upgrade to 4.4.2 this little trick does not work anymore. When trying to go to the admin-page I get this XML parsing error, so I cannot access the admin-page.

My friend who is more well versed with these kinds of issues says that our server is configured correctly, and the fault is with Wordpress. I asked for help on the forum and did not get anything useful, I appreciate if you could help me with this.

I just noticed another error also:

XML Parsing Error: not well-formed Location: https://www.ftek.se/main/wp-admin/update-core.php Line Number 52, Column 82:

Hello @ingstra, welcome to Trac!

Can you please provide some info about your server and your browser? It seems like something is serving the pages as XML rather than HTML.

Thank you, and what a quick reply!

What do you need to know? Here is some information I can think of: The server is running Debian Wheezy, kernel 3.2.0-4-amd64, Apache/2.2.29, PHP 5.6.6. My current browser is Firefox 38.5.0. I tried Chrome on my cellphone as well, where I currently get the error "error on line 10 at column 27: Entity 'lsaquo' not defined"

This feels like the html_type option is potentially set to xhtml, common in the days where XHTML looked like the future of the web.

@ingstra Can you let us know what the value of html_type at https://www.ftek.se/main/wp-admin/options.php is?
Unless you're doing something special and particular, that should be set to text/html.

That option should probably be removed realistically.

I'm not sure I looked at the right place, as I couldn't find the 'html_type' option at https://www.ftek.se/main/wp-admin/options.php. But I looked directly in the database:

mysql> select * from wp_options where option_name='html_type';
| option_id | option_name | option_value | autoload |
|        49 | html_type   | text/html    | yes      |

Is there any progress on this matter? A friend who is more well versed in these areas than I am suggests the use of numerical entities instead.

  • Resolution set to wontfix
  • Status changed from new to closed

Finally, after over a year of having trouble with this, I found that the problem disappeared when I set html_type to applicationxhtml+xml.
