What risk would I run updating very old D7 sites to their most up to date D7 core and contrib code and module versions?
A little background,
Starting in 2011, I was a senior developer on a team that, over the course of 6 years, created and managed 20 or so enterprise-level D7 sites. Some of these were national level chains, some of them were major universities. Given that they had already invested so much in D7, less than a handful decided to go D8+. The rest decided to ride the D7 wave until EOL.
I am trying to design a newsletter with the simplenews and Simplenews Content Selection modules. The newsletter has a header -logo, slogan ...- a body with two columns of blog articles and a footer -social networks, collaborators ...-. To do this, in the simplenews content type I added a header field and a markup footer with their content and the body content is generated with SCS.
Sorry I've not found the solution to my issues in the support forum
I have 2 shared hosting instances with the same hosting company (linux), I have a drupal intranet for students (Drupal 7 latest version of today) and I had to relocate the website to another server, more or less the same (so says the hoster)
All my ajax callbacks don't work anymore (file removal, adding in custom content types, pictures, even views like admin/people does not refresh correctly if I hit "filter" and I have to refresh the page to get the result)
I do not have a lot of experience with Drupal. I have a development site and production site. When I try to login to to my development site, it redirects to the production, making the development unusable. Can someone help me find the file I need to edit my theme to change the path to relative?
