re: Now I would like to make minor changes in the look. Still have to swap the appearance of City and zip-code.
I answered the same question in this reply. What I did was edit the page making the change to the shortcode so you can see how it is done.
re: Which is the right file to make changes?
It is not necessary to edit the file directly and advise against it so you are able to upgrade. Please see how to make changes in an update safe way:
re: Maybe change the color
See this page on how to do it. No files need to be edited.
re: change the typo
The font style is picked up from the theme. It is not set by template. So if you want to change the font style, change it in the theme or use the custom CSS file to set one specifically for the template.
re: Would also like to translate the words “select category” in the dropdown menue.
I change the shortcode so you can see how this is done. I do not know German so I use Google Translate. You’ll need to tweak to make it correct.
re: How do I activate the picture?
I answered the same question in this reply. I updated the shortcode to configure cMap to display the photo instead of the logo.
re: when all entries are shown in the dashboard I see the alphabeth on top. Not all letters are shown. It stopps with the letter V.
I see all letters. Make sure the filters in the top left are all set to show all. Also, by default, the list is paginated showing only 50 at a time. Make sure you click to go to the next page.
re: And what I would like to know most: what have you done, to bring everything back to life, that I could not? Could I have fixed it myself?
I had to figure out exactly what shape your DB was in and then manually edit the PHP files to run the right update routines. This would have been extremely difficult to do yourself if you’re not a PHP expert and have a deep knowledge of the Connections code.
Hope that helps!
