[Users] Base Layer Does Not Display on Initial Load

[Sarah Schuessler]

Without any code we can`t say anything.
Did you checked misspelling, code mistakes?

best regards
Sarah

Betreff: Re: [Users] Base Layer Does Not Display on Initial Load

Also if it helps any, I'm getting the following errors in my firebug console...

OpenLayers is not defined
symbolizers: [OpenLayers.Feature.Vector.style["default"]], Featur...erer.js 
(line 36)


OpenLayers is not defined
"eq": OpenLayers.Filter.Comparison.EQUAL_TO, form.js (line 78)

I've yet to conquer this issue so any other advices would be great and very much 
appreciated :)

Thank you,

elshae
