And by moving my article_page.tpl to override/templates/ folder, the template is shown. But my debug output still gives me some errors like:
Error: eZTemplate @ extension/ezwebin/design/ezwebin/override/templates/page_article.tpl:12[12] Cannot retrieve attribute of a string
Error: eZTemplate @ extension/ezwebin/design/ezwebin/override/templates/page_article.tpl:19[8] Jun 09 2010 18:50:49 Cannot retrieve attribute of a string
The code in page_article.tpl is identical to the code in article.tpl
That highly depends on what you have on line 12 and 19 in that template (So yes, always post the lines of code you have issues with so people can help you, what code is on which line changes from version to version, so always post the line in question and a few lines above and bellow if it seems to be several lines involved in what ever happens on the lines something breaks).
Looked in full/article.tpl in webin, but there are no tpl code on line 12 so guess you made some changes. Additionally, if your class is different then article class, that probably explains it as well.
Sorry about that. I thought it might have something to do with some configuration. There is a lot of that in here :) Yes, I have done a few changes. This is my code and starts at line 8:
