Hi there, I'm new to the site so please forgive me if I repreat whatever has been said on the topic here before. After months of adding pictures to articles in K2 (Joomla 2.5.9) smoothly, a month ago I noticed a problem that wouldn't go away since then. I cannot insert new pictures. All I get on the screen are similar long messages that even my K2 site developer cannot inerpret. Could you please help? Any pointers?

Here are 4 recent (very similar) messages that I have got after failing to insert pictures (photos):
