Solved the problem. Thanks.
I had this problem a while ago and the info on that page fixed the problem, but the problem happened again today and that fix is no longer working. Now I can't upload anything thanks to Dreamweaver's internal data error. I can connect to my web site using a different program, so the server can't be blamed. I even restarted my Windows 7 computer to see if that would help, but it didn't.
Which Anti-virus and Firewall are you using?
When DW starts acting weird, the first thing to try is Deleting Corrupted Cache in DW
If that doesn't help, try Restore Preferences
If all else fails, use the CC Cleaner Tools below followed by a software re-install.
I'm using Dreamweaver CS6 on a Windows 7 PC. I use Avast antivirus and Comodo firewall. As far as I know, nothing has changed with the antivirus and firewall.
Deleting the WinFileCache file fixed the problem last time (a month or two ago), but this time deleting it didn't help.
I also just renamed the Configuration folder so Dreamweaver would make a new folder, but that didn't help either.
The page about restoring Dreamweaver preferences is for earlier versions of Dreamweaver, so the places the page says to look don't seem to be there.
Rename the Preferences folder:
1) Close Dreamweaver.
On Mac : ~/Library/Application support/Adobe
On Windows7 : \Users\<user name>\AppData\Roaming\Adobe
2) Rename “Dreamweaver CC2014.1” to “Dreamweaver CC2014.1_old”
3) Re launch Dreamweaver.
Thanks, but that doesn't seem to be in the Adobe folder. Here is a list of what I see:
Extension Manager CS6
OK. Looks like you have CS6; not CC 2014.1 (the latest one).
Be sure to turn hidden files and folders on in your File Manager.
OK, I renamed the folder "Dreamweaver CS6" to "Dreamweaver CS6_old" and started Dreamweaver. A new "Dreamweaver CS6" folder was created and I was able to connect to my web site.
As an experiment, I closed Dreamweaver, renamed the new "Dreamweaver CS6" folder to "Dreamweaver CS6_new" and renamed "Dreamweaver CS6_old" back to "Dreamweaver CS6" then started Dreamweaver again. It's still connecting to my web site. Now I won't lose my settings!
Thanks for the help. Now I won't feel like somebody kicked me in the stomach.
Glad you got it all sorted .
I have a new Windows 8 computer and I got that stupid FTP internal data error with Dreamweaver CS6 today. The fixes that worked before on my Windows 7 computer are no longer working. I'm getting pretty tired of this. Does anyone know if there will be any more updates to Dreamweaver CS6 that will fix this work-ending problem?
If I can't upload my pages to my web site, what was the point of spending so much money on Dreamweaver? Can anyone recommend something better than Dreamweaver that isn't so buggy?
Does anyone know if there will be any more updates to Dreamweaver CS6...
Not likely. CS6 is legacy software (7 versions behind the current CC 2015). CS6 no longer qualifies for Adobe support or updates.
That said, I have no problems connecting CS6 to my various web servers. I suspect the FTP problems you are having in Win8 may be permissions related.
Are you able to connect to your server with a 3rd party FTP app like FileZilla?
It was working perfectly for over a month, then it developed the same problems that happened on my Windows 7 computer. I discovered this morning that it will randomly upload if I keep deleting the Dreamweaver CS6 folder after closing Dreamweaver, but that's not a very good solution when working with over 100 pages of a web site. Having no guarantee that closing and deleting will work from one moment to the next isn't a fun way to work on a web site.
Obviously you have a corruption somewhere.
#1 Export your site definition settings to STE files and save in a safe location.
#2 Copy your custom snippets folder (if you have any) and save in a safe location.
#3 Run the CS Cleaner tools to wipe all traces of DW CS6 off your system.
#4 Re-Install DW CS6.
#5 Be sure to install the last 12.0.3 update.
Thanks. For the rest of the day, so far, the error hasn't returned. I'll do what you posted if the problem comes back.
