I purchases Housez theme and can´t upload images for properties. I have watched tutorials but on the tutorials their is an upload image button, but on mine there is not.
Please contact the author of your purchased theme, the author will assist you.
How to contact an author to get support or for any technical query:
You need to update to Houzez v220.127.116.11 and Houzez Theme Functionality plugin v2.8.4. Have you done this? If so, then maybe caching is the issue. Otherwise as @mgscoder has said to contact the author.
