Fatal error: Cannot call overloaded function fo/wp-includes/user.php on line 217

This is either related or a coincidence, I too had this issue on the one and only Godaddy site I manage.
Somehow (maybe my fault) when I installed wp it assigned my username as “admin” .. I’ve done hundreds of installs and always use the same username, never admin, but perhaps I forgot this time and it defaulted..
Anyway, I changed my username with a plugin. Then when I would log in, I’d get a broken page (no css) but If I clicked a link it was the site as usual.

This is exactly when I started getting the same error you describe.

And wp-includes/user.php on line 217 is something like get_current_user.

So I switched my user name back to admin yesterday and haven’t seen the error again, even after extensive work on the site.

Guys, we had similar problem when we write our firewall plugin for wordpress, and find that this is related to the APC module for Apache, to resolve it, simply edit your php.ini to uncomment the apc module so it reads from

extension=apc.so

to

;extension=apc.so

This will resolve the problem.

In Godaddy’s cPanel you can create a new file in the public_html folder and save the file as php.ini

Then right click on that file php.ini click edit (once) then click edit again (second screen)

type

;extension=apc.so

Save Changes

Or you can create the file in a text editor (Notepad) upload to public_html using FileZilla

After reading a bit and researching, it does seem that the problem is with Godaddy and their configuration with Apache. I have no clue what it is but I have installed lots of WordPress sites with no problems on other hosts. One thing I want to point out that maybe this is why some of us are getting this error, is that I didn’t install WordPress from scratch, or from the wizard. I did it from the duplicator plugin, which I think is great. Anyways, I fixed it using James solution, creating a php.ini file on the root and commenting that apache module.

Hi,

I agree with Zed. I am also using GoDaddy Shared Hosting for my wordpress website. However, I have noticed that I only get this error occasionally, due to heavy load on website. The error appears when there are more visitors on website than normal. Then, it goes away automatically.
