# tikz externalize optimizes pictures away although jobname complies [closed]

I used tikz externalize successfully for a time now. But since my pc crashed once the externalized pictures are instantly deleted. Reading the manual I found out, that they are "optimized away" because of the jobname differing of the documents (?) jobname. I did not change anything here. How can I fix that?

Here's the log of the main tex-file:

The log pretty much says it all, you have optimize=\false where it should have been optimize=false. If they were already externalised then this is also why it worked before, it found the image and never came to this code. – zeroth Apr 7 '12 at 20:23
Sorry, I posted the wrong log. Now I changed it to the log of the main tex-file without using the optimizer=false tag. Firstly because I don't want to use it and it didn't work either. And externalizing worked well: to update a specific picture I removed it or used "tikzexternalizedisable". – severin Apr 7 '12 at 21:06
It is not clear from the log where the error lies, however, it clearly states that the externalised objects are errorneous. Please supply: bilder/ext/diplom-figure3.log or any of the other externalised images, they contain the error. – zeroth Apr 7 '12 at 21:14
Just guessing but did you register/ sync your dropbox folder recently after the crash? Looks like a system problem instead of LaTeX related... – percusse Apr 7 '12 at 21:19
After investigating I tracked down the problem to the following code: \begin{enumerate} \item "asdf"' \end{enumerate}` Seems like this interferes with shell-escape tikz-externalize uses. (Not allowed to answer my own question, although this is the solution. So someone could answer this :-)) – severin Apr 7 '12 at 22:04
