Update Wordpress Theme + Fixing Pagination + Fixing Twitter card and other issues

Project - Update Theme + Pagination + Twitter Cards/Facebook preview + Affiliate-Link-Buttom Update + The Main Menue should + Overlay magnifying glass Hi there, I need a little help on my blog [login to view URL] (hosted at [login to view URL], nginx server, Enfold Theme). 1. Update Theme: A few days ago I updated the blog to WordPress 4.7.2. Since that day the pagination does not work anymore. For example: [login to view URL] shows the same posts like [login to view URL] or [login to view URL] shows the same posts like [login to view URL] My host identified the theme to be responsible for this problem. My theme support says: „A new Version (3.8.5) of your Parent Theme (Enfold) is available! You are using Version 3.0.4.“ Exactly here I need help. I am afraid to update the theme, because before freelancers changed different things. So I guess that there might come up especially layout problems after updating the theme (even though I am using a child theme). So what I want it, somebody who can fix all the issues after updating the theme, to make the page look the same way it does look right now (before updating the theme). And of course the pagination should work again. The update should be started around Midnight (western european time), so that hopefully in the morning the blog is working fine again. Unfortunately I do not know how much work will come up after updating. Maybe nothing…maybe a lot….. 2. Fixing the not working pagination I would like to fix also a longer existing problem: I think for SE0-Reasons I should use rel=“next“ und rel=“prev“ for all pages (there are around 33 different pages where this need to be done). Perfectly pages, that I might create in the future automatically have this rel=“next“ und rel=“prev“ attribute. As far I understand rel=“next“ und rel=“prev“ helps to avoid doubled Title-Tags and Meta-Descriptions on Google Search Console like for example: Doubled "title"-Tag: Le migliori offerte sottocosto online del giorno. /i-migliori-prezzi-dalla-pubblicita-di-cartoonito/page/2/ /i-migliori-prezzi-dalla-pubblicita-di-cartoonito/page/3/ /i-migliori-prezzi-dalla-pubblicita-di-cartoonito/page/5/ /i-migliori-prezzi-dalla-pubblicita-di-cartoonito/page/8/ /offerte-lego/page/7/ /offerte-sottocosto-mediaworld/page/2/ Also I think it make sense to have only for example [login to view URL] (Best Lego deals) in the google index. Right now you can find also [login to view URL] etc. in the google Index. I think this is not good...? Other suggestions to solve this problem are welcome. 3. Twitter Cards: Right now there is on Twitter always a product image + a little summary. I do not need this summary. Only the pic (which size should have the pic to be always expand on Twitter Time-Line?). Same issue I need you to fix on Facebook. 4. Every posts right now has two affiliate Link Buttons: „Mostra Offerta“ and „Vai all'offerta“. I think it is better (SEO-Reasons) to have less outgoing Affliliate Links. So the „Vai all'offerta“ should be deleted. The button „Mostra Offerta“ should say instead „Vai allo Shop“ For the user experience I think that 2 buttons are better.....but every seo-tool tells me to reduce external links.... 5. The Main Menue „Offerte del Giorno / Home Giocattoli - Saldi invernali / Buoni " - should get a more readable font. Please make suggestions and implement them 6. The Overlay of the magnifying glass on frontage is not working fine. I need it to be fixed the way the magnifying glass is always visible. If you make a good job further cooperation is definitely possible. Greetings Thomas
