Messed up after upgrade

[purepixels]

Hello everybody,

 

I'm currently working on a new webshop and everything went very well. Untill I tried importing a list of products. Due to a problem with the import function I tried upgrading my prestashop installation from 1.4.8.2 to 1.4.9.0. After that, nothing did work anymore. I decided to recover the old installation by removing all files and replace it with a backup I made just before upgrading (messing up) my webshop.

 

After a backup that I installed, I only get the following output;

 

 

<!-- Block categories module --> <div id="categories_block_left" class="block"> <h4>Collectie</h4> <div class="block_content"> <ul class="tree dhtml">

 

This is the complete source, there is nothing else anymore. Is there anyone who can help me recovering the complete webshop?

 

Thanks in advance!
