javascript - OpenLayers (2.13.1) zoom/pan has stopped working -


i have legacy product utilises older version of openlayers (specifically 2.13.1 - had on sversion 2.12 , upgraded 2.13.1 see if rectified problem - didn't).

the problem recently, without code changes having been made, zoom in/out , drag-panning not work - map stays is, zoomed in @ initial level.

i can see whenever zoom or pan controls triggered, request made google maps url (e.g. http://maps.googleapis.com/maps/api/js/staticmapservice.getmapimage?1m2&1i524027&2i524088&2e2&3u12&4m2&1u523&2u400&5m5&1e3&5sen-us&6sus&10b1&12b1&token=39368)

however can see returns blank, black image.

i can find no sign of functionality having been deprecated , i'd avoid inherent time cost of upgrading version 3 on legacy application.

any ideas? appreciated.
