Yes, i found some problems in tag cloud plugin include title problem you mentioned.
If you go to Basic settings>tag cloud , you'll see two important parameters.
1. Tag minimum length. default value is 3
It means the minimum tag length for using by the plugin is 3 characters.
Tag example : Sell car in sydney
The plugin gathers all listings which contain these words: sell,car,sydney
It should not gathers listings with 'in' word because minimum tag length is 3
But unfortunately plugin does not work properly with this parameter and you can imagine what will happen.
Solution: Go to plugins/tag_cloud/rlTagCloud.class.php
Find: tc_tag_min_symbols
Replace with: tc_tag_min_length
2. Banned words
If you add words like 'the,this,that,what,which,who,...' and your tag cloud is 'the best car price'
So it prevents gathering listings which contain 'the' word.
It seems, this part of code work properly, but do not forget to use this parameter.
3. Missing title as you mentioned. Go to plugins/tag_cloud/tags.inc.php
Find:
Code:
Only registered members can view the code.
Replace with:
Code:
Only registered members can view the code.
I think tag cloud needs a whole investigation.
