This message means, that your website does not recognize some expression from the PHP.
Please be sure that:
1) Your WP is up to date
2) Your PHP Version is 7 or higher.
I see, that your theme is very old, please update it first:
Here is an instruction on how to update the theme: http://themes.muffingroup.com/betheme/documentation/#general Theme updates will not delete your content unless you have changed the files directly in which case we suggest using a child theme. We also recommend creating a backup file. Please remove the theme completely from your theme folder and install a fresh copy. Do not overwrite files.
First this now appears at the top of the page "UA-92306954-1" I think I have had this issue before, The host may have corrected the issue, but thought I would toss it in here.
Second, I seem to have two Sliders on the home page at klad.com They should be the same size, BUT one appears larger and it is the second that is specified in the settings??
1) I do not see that text on homepage on klad.com, did you solve it?
2) On the second slider, please edit the section (section settings) where this item is inserted and turn on the "full width" option on the bottom of these settings.
