Dear friends, I'm configuring my Prestashop (1.6.0.9, theme default-bootstrap version 1.0) and suddenly a part of banners and texts is being displayed significantly smaller, than before (good to see on the lower part of screenshot). I've tried already to clean cash (also in the theme) and to switch off cash and turn on "force compilation", but no results. The only reason I can think of is removing (then putting back) page "index" in PREFERENCES/SEO&URL just before it appeared (was attempt to remove "/index.php?" from the address line) Do somebody have any idea how to fix wrong display? Many thanks in advance Albert
