HAIRWEBSHOP Posted May 4, 2016 Share Posted May 4, 2016 (edited) Hello, After adding a slider image, Prestashop does not show anything on the front office other than the logo and the grey footer image of the default bootstrap theme. I tried disabling the homepage slider, but that didn't work. When I go to the theme in the back office it will output the following error. Warning op lijn 2607 in bestand /path/htdocs/www/hwtemp/tools/htmlpurifier/HTMLPurifier.standalone.php [512] Cannot retrieve value of undefined directive Core.CollectError invoked on line 7474 in file /home/vhosting/b/vhost0072918/domains/hairwebshop.nl/htdocs/www/hwtemp/tools/htmlpurifier/HTMLPurifier.standalone.php Can someone please help me figure out what's going on?Thank you in advance!

ernexus Posted May 4, 2016 Share Posted May 4, 2016 Well, possibly yes. They are using HTMLPurifier, which ensures standards-compliant output. Meaning it may change your output and for some reason it could broke. Link to comment Share on other sites More sharing options...

ernexus Posted May 4, 2016 Share Posted May 4, 2016 You could look for your server error logs, it may logged some fatal php errors. Link to comment Share on other sites More sharing options...
