I've been trying numerous things over the course of a couple of months where this problem started, like :
I also tried launching chrome as admin, added Everyone in pepperflash security options with full privileges. Nothing has worked so far. Flash simply refuses to play on many websites. I can't even load a pdf, it displays this message. I don't have suspicious plugins installed (like adblock etc). Is there a way to fix this? Thanks in advance.

Open Chrome and Go to "Advanced Settings" (Settings > Show Advanced Settings). Now click "Content Settings" button under Privacy section. In the end, go to Plugins section, click "Manage individual plugins" button and disable “Shockwave Flash 14.0 r0“.
I encountered the similar error and got rid of it by disabling this "Shockwave Flash 14.0" plugin. This happens when two different versions of Shockwave Flash works at the same time.
I believe I found the problem. I noticed that I had two flash version APIs installed: NPAPI & PPAPI. I found out that NPAPI is now deprecated, so I uninstalled it. Now I have only PPAPI. I have tested this for about 5 days now and everything seems to work fine ever since I uninstalled NPAPI. Hopefully this may help someone.

The solution above was the real deal (and found it myself).
