We have some issues about wordpress themes we bought at theme forest and CiviCRM. When i google I find a a lot of same problems other users have with the CiviCRM backend and some wordpress themes. Before I buy any new one I really wanna be sure that there are no problems with CiviCRM. Is there any list of compatible wordpress themes somewhere here? Or what kind of creative themes do you guys use together with CiviCRM? Thanks for any suggestions and help.
Assuming you are using the latest and greatest Civi and Wordpress - most themes should work fine.
There was an issue with backbone conflicts that may have caused issues with some themes- but that was addressed in 4.7.31. Outside of that - I never had an issue with the CiviCRM backend when using any front end theme. However, I have had conflicting CSS on the front end that can typically be fixed by changing some lines in your CSS.
As for what theme I use - a modified version of twentyseventeen.
