Embeded code instead of text. No support

This is how it went for me:

—————–
It worked almost fine at first then it started displaying code at top of page next to post categories and in post summary, instead of summary of content, which was text. I have deleted for now and will try again on a test page again, but now the following coding remains:

otw_grid_manager_content: []

I haven’t deleted the sidebar yet but the contents have been removed from widgets. What a polavva! I used the text widget and placed it inside one of the widgetise sidebars. Then i placed text directly inside the text widget, as it should be seen with no formatting. Although all i can think of that I did wrong was perhaps i copied and pasted the text from the page and this caused some kind of formatting/code error….? Maybe I should have turned it to plain text. Am i barking up the wrong tree?

Can anyone advise please?

I got no response and so had to delete page and start again with different editor.

Ultimate TinyMCE looks quite good so far. ??
