Modules in sidebar overlap

Hi,

i have 5 modules in the sidebar position of my website and the issue, that from time to time they overlap.
in fact i think it is always the module with the twitter widget in it that gets covered by one or two other modules...
does someone know how i can fix this?

Thank you very much!

Could you please post an url to your site?

but it doesn't happen all the time...

And if i'm already writing here, i have another issue but this time with the Tabs GK5 Module:
it's nice and finde on the home page, but on all the other sites its way to wide and i can't find a way to keep it at the same width as all the other sidebar modules. Do you have an idea what could be the problem here?

thank you very much!

Please try removing triple module suffix from this module.

AWESOME! Did work perfectly! Thank you soo much! Best support ever!!

Is there anything else I can help you with regarding this topic?

No, this topic is perfectly solved Thank you so much! I'll add a good review on joomla.org for the module! Thank you very very much!
