CMS Made Simple Forums

I'm using: 1.10.3 "Hyacinthe"

I installed FacebookLikeButton: http://dev.cmsmadesimple.org/projects/likebutton

I created global content block, that included:

<div class="facebook">{FacebookLikeButton font='verdana' colorscheme='light' lang='sl_SI' send='false'}</div>

Since the install I frequently get this error message, that disappears after refreshing the site:

string(101) "Smarty error: [in tpl_body:24 line 3]: [plugin] unknown tag - 'var' (core.load_plugins.php, line 198)" string(113) "Smarty error: [in tpl_body:24 line 3]: syntax error: unrecognized tag 'var' (Smarty_Compiler.class.php, line 590)"

Any ideas on what could be the problem here?

Probably some javascript that is not enclosed by {literal}...{/literal} tags.

That did the trick, thank you.
