One Twitter widget is embedded on our two home pages - different URLs, identical structure (in HTML4 Transitional), identical copies of the widget code. Both pages work fine in all browsers, EXCEPT that in ONE page the widget causes mobile Safari (iPhone, iPad) to fail to fully load the page. The table cell containing the widget flashes up then disappears, and the rest of the page stops loading. Both home pages are large, but the one that fails is the smaller of the two.
What do I look at next, please?
