Blank Categories Pages

[gabiatti]

I saw a lot of topics about blank pages, but nothing help me.

 

Some of my categories (4 out of 27) shows a white/empty page and HTML code. Those are not new categories. 

 

All others are working as expected

 

Try to debug but there's no error to show 

 

The page is: http://www.lcsmotorparts.com/ and its multi-language. Portuguese (default) and Spanish behavior as above, English page does not open any category.

 

 

 

PS version is 1.5.5.0, I upgraded from 1.5.4.1 recently, but never notice that problem before.

Not using layered navigation. Random products in homepage not causing the problem.

Default theme with minor CSS adjusts.

Now I could turn on debug - error in English Categories *Portuguese and Spanish versions don't show any error, just open a blank page:

Delete cache/class_index.php

rename the friendly urls in categories.

 

Problem is solved.
