All sliders doesnt work at page by PrestaShop 1.6

[MicroSpace]

Hello

In short: all slider-modules just stopped working. They are simply deployed instead of a slideshow.

1. slider on the main one (Cs Slider Camera; completely gone)
2. List of products on the main (Cs Featured Products by Category)
3. best sellers (CS Top seller block)
4. block manufacturers

How did this happen?:
I tried on the site which is made on PrestaShop 1.6 (https://koniaka.com.ua/) to install a new module from the admin panel (Watermark v1.1.0 - by PrestaShop). In the admin clicked "Install" and immediately the site went down with the error "500 (Internal Server Error)"

From FTP i was deleted folder with this module but it did not solve the problem.

Then I found the information in Google that I needed to edit the .htacces file (change the Options + FollowSymLinks  to Options + SymLinksIfOwnerMatch) and it all worked. But it happened. Sliders do not work and just hang in expanded.

 

backups restored and cache cleaned

console:

 

Help me please with this problem

Looks like something funny is going on in header.tpl. 

 

			var priceDisplayMethod = {
				$priceDisplay
			};

As far as I know that variable is only available in the product page. It might be a module, but it's hard to tell. See what hooks before "codespot" in the header hook

Sorry, but i dont understand. What does it mean "codespot".

At "displayHeader"-hook i have a 35 modules

Codespot might be the CS static block
