Solution to title problem

I just used several hours to fix that…

You may open the css file of the plugin

.categoryThumbnailList .categoryThumbnailList_item {
width:150px;
height:150px;
display:inline;
float:left;
margin:0px 10px 10px 0px;
text-align:left;
overflow:hidden;

Try to change the height to 200px
And you will see the words appear again
