I supposed I do have some basic coding skill. (...Have to say I am a girl who is not really good at that...) But what happen is that even if I try to embed my tumblr the same issue still occur.
According to Vaska - "You will need to customize it - make a copy of the plugin and put it in your theme folder. Then, you can make all the changes you want/need for it and it will override the default version. --> So does it mean I have to amend it in Admin or go directly to my FTP to amend it?
You can either give the plugin (javascript) a standard height (say, 800px) or you can use the height of the browser window. It's not as hard as it sounds to customise...let us know how it goes."
Hmmm....I am just stuck from the first step really. Do you think you could help me? Thank you so so much arsondpi!
