page à propos blanche, "Warning: htmlspecialchars() blabla " problem

[gluontronic]

I just figured out something while trying to update my "à propos" page: I cannot display ANYTHING from the CMS pages part. Everything seems ok but the middle of the page is blank.

 

I activated debug mode in config.inc.php ( @ini_set('display_errors', 'on'); )

and here is the cute error.

 

 

Warning: htmlspecialchars() expects parameter 1 to be string, array given in .../tools/smarty/plugins/modifier.escape.php on line 44

 

 

Any tips ?

Is it something I'll discover a bit everywhere on the website or is it just a small problem ?

 

I can fix it if there is a code fix but I just want to USE prestashop, not to DEBUG it each day of my life, focusing on the core.
