Hi,
I had a notification that I needed to updated my PHP to at least 5.6 as it won't receive security updates from Joomla otherwise..
The problem is it means I get a blank website and when I checked with host they said it was an error regarding rokspoket... Has anyone come across this and what to do? My website it mainly based on using the mosaic and grids from rokspoket... Thanks

Hi there,
which PHP version is running right now? 7 oder 7.1

1.) Install the newest version of roksprcocket or update the component from Joomla update page
2.) Enable the error reporting to maximum to show the error instead of a white site

I was on 5.3, but changed it to 5.6 as it requested. I have done what you mentioned below and the error message is as follows;
Fatal error: Call to undefined function mb_split() in ***** /components/com_roksprocket/lib/RokSprocket/Util/HTMLManipulator.php on line 36

The roksprocket is up to date.

If I change the php to 7 then I get the 'unhappy face error' Error: 0
Call to undefined function mb_split()

Any suggestions on what I can do?

Some provider are using PHP preg_split instead of mb_split
Edit the php file >
/components/com_roksprocket/lib/RokSprocket/Util/HTMLManipulator.php on line 36
Line 36 and change from

$tokens = mb_split("\s+", $content);

to

$tokens = preg_split("/\s+/", $content);

Thanks so much that worked
