Drupal 7.x

Hallo, I am using a panel node for my home Page in  D7. Even when I set the meta tags for indexing to "index,follow" the result HTML report "noindex,nofollow". 

I tried to clear cache but It doesn't solve the problem, do you have ant suggestion ?

I'm trying to setting up a real estate portal and I need to figure out which way might be the best one for the following operations with exposed filters views, searching, facet, etc.

I am very undecided on which way to choose. My instinct would be to do it through a referenced node for each house, but I was considering the hypothesis (to make it more convenient and faster for the user to enter data) the use of Paragraph.

Sometimes, during development, it happened that the views gave a json problem.
Once, in an editable view, but I was able to understand that the problem was that it must not have the cache.
Other times, without understanding why, this happened in normal views by saving settings or simply adding fields to an already existing view. In these cases I solved it by going back to the previous backup.

But the reality is that I can't understand "what" should be avoided (apart from the conflictiong modules) in order not to get these problems.

Hello,

I am a marketer and I have 5 subdomains in drupal 7 of around 100 pages each. I want to migrate my subdomains to Drupal 8 and I was wondering how much time would that take. Can any one of you please give me an estimated time? I'm also planning to redesign my sites so I require adding some new paragraphs but they won't be many, may be around 8 to 10 new paragraphs.

How much time do you think it should take?

Thank you very much in advance.

I have defined a content type which includes a date field. When I use this as an exposed filter in views I get extra settings including "Selection form element" and "Filter granularity".

I have also defined a custom table to views using hook_views_data. This includes a date field defined as follows:
