I've upgraded from 4.2 to 4.5 in single upgrades (4.2->4.3 etc.). After the final upgrade, the indexed search displays the html and js code of some content blocks in the search results. Not all though. I can't find a pattern for that. I moved the HTML block to the bottom, in case it now simply displays the top most block, I emptied all tables that start with index_ to make sure it renders the index new, i emptied my browser's cache, it still displays html and js code.
I compared it to a node, that is displayed correctly as a result, the html block is top most, the code is the same, just two pictures were added for a image slider, Access and Appearance have the same settings.
Any idea what's causing that behavior? someone experienced the same thing?
