Cannot buy anything from traders?

There is nothing suspicious in logs. Look like you've fucked up something while manually editing your profile.

All money in the game are not virtual numbers, but have actual representation in your inventory - there are stacks of bills with maximum limit (500k for Roubles, 50k for Euro and Dollars). Look like after your editing game cannot see you have any money because you increased stack amount over it's maximum without changing allowed maximum or messed with something else.

Only advice - revert your changes (hopefully you have backup)

Just to idiot check, you clicked the box at the bottom of the page to add your items (in this case roubles) to the trade?
(I have seen this a few times reported so just checking obvious solutions)
