Wordpress Error : Call to undefined function

wordpress

Here’s a quick heads up for those of you who encounter this error when you upgrade your wordpress (especially for those who upgrade to Wordpress 2.3.1). If you see this error after replacing the old wordpress files with the new ones:

Call to undefined function: _make_cat_compat() in /home/hongkiat/public/blog/wp-includes/category-template.php

This is probably caused by the file category-template.php. Try re-upload the category-template.php file, and it should be fine.

just as an addendum:
i’ve just encountered another instance of “call to undefined function” error when i installed a plugin called events calendar.
after few hours of google, finally found out it is due to “short tags” problem.
in short it means wordpress fails to read ” < ? ” as a php tag.
so i just change all instances of ” < ? ” to ” “.
problem solved. =)

You’re advise to backup before overwrite any file.

I recently upgraded to 2.3.1. Did not get this error but I got one while using TAG which was due to SEO title tag. I was using the previous version of it which uses UTW

I already have wordpress with version 2.7. Previously, the wordpress running well, but right now I can’t reply comment, font at Post became white only, and etc. I already try with upgrade to version 2.8.4, but the problem still exist. And then, I already try to open with different browser. When at IE browser, I see Error on Page at bottom left sidebar. It says ‘commentReply’ is undefined at wp-admin/edit-comments.php line 268.

Please you can help me with this problem. I also already search at Google about this error message, but I found nothing.

Thanks
