A week ago I bought a NewYork template that I want to install in

environment: PHP 7.1, Prestashop v1.7.5.0, theme: New York: Super Market 1 but:
- I installed Prestashop, I made modules update by Module Manager / Updates, I installed the language: German and English (the site must be in 3 languages PL, DE, EN)
- I made thumbnail generation, in Field Theme Customizer I made Refresh Table and cleaned the cache,
- I installed the Super Market 1 template
- when the template was activated, an error occurred and an attempt to enter the shop's website has caused an error (probably something from Smart Blog - incompatible?!?!)
- I turned off Smart Blog - the site has now started
- I made again the generation of miniatures, in the Field Theme Customizer I made Refresh Table and cleaned the cache,
- after entering the site the search does not work: eg I type the word Mountain does not return me products with this word, only when I press enter to display the list of products - I have chosen the language PL, i.e. my default
- if I choose a website in German, for example, the search also does not work either for hints or for pressing Enter, it also does not display products
- I added two categories to one of the subcategories and threw the products into them but I also do not search for them
- another thing is a problem with Menage Verical Megamenu: I added my created categories Antique and Dwarfs - added and displayed but how do I want to add a subcategory or enter the Krasnale in Content activate and select in the Main Section your subcategories Big, Small, Medium return to Main Menu I go again and what I did is inactive again as if it did not save, also if I want to set the icon in icon class, for example fa fa-home also does not save

I am asking for help - I spent the entire weekend, I tried various combinations and I can not go with the website - in total it will be a catalog of about 1000 products - without prices and ordering options (for now :)).
Correctly the site only worked as I installed the QuickStart version but it was enough to update Presta to 1.7.5.0 using 1-Click Upgrade and stopped searching again, added in Menage Verical Megamenu and after adding additional languages did not display all modules after switching to the added language eg footer is the lack of Contact Us, Information etc. was visible from what I remember only OUR NEWSLETTER.
HELP ME !!!

As for the Smartblog module, I used a solution that you have indicated but did not bring a rare positive effect, it still displays the error. I downloaded and installed version 3.0 from https://github.com/smartdatasoft/smartblog/releases, but when I enter Configure, it shows me the same error as before (photo attached) and I still do not see the management panel on the left on bottom, below FieldsTheme Configure - where it should be.

ok problem with Smartblog solved :) what I did:

- I turned off the module and uninstalled it
- I installed Smartblog v3.0 and it works - so simple haha
so far it is displayed in the panel I can enter its configuration and how it will go on, i.e. posting etc. will come out at work ...

Edna - now I am waiting for positive information from you about the correct operation of Menage Verical Megamenu and search on the site

Hi Edna,

so now Vertical Megamenu works great :), there is still the problem of product search (by name or index), which is very important to us ...

Hi Edna,

now the product search works ... yeaaah good job - well if you correct it in the templates that are downloaded because if I had to re-install on the server then I would have to turn your head back again ...
Sincerely
Marcin
