Hi Stefan,

I just moved my site to a new DNN installation, on DNN 04.05.05 (can't upgrade past the yet because some modules we are using do not yet work on 4.8.2. I desperately want to move up to solve  the xml timeout issue that is supposed to be fixed in 4.7 and above)

I have XML module 04.03.04 installed.

2 times now, I have had the xml and xsl source settings disappear on me. This has always been when I have set it to a static / local xml or xsl file. The module instance seems to lose the file reference and the module then displays nothing. Yesterday it happened on every instance of the xml module on my site. All the parameter settings were still in place, but the references to the xsl files (local in the portal root) and some local xml files as well, all were lost and I had to reset them all by hand. The files were all still there.
  XML Data Source Settings
 File: File Location: Root _old/
 File Name: table_Country_Codes.xml
  XSL Transformation Settings
 File: File Location: Root _old/
 File Name: select_Country_Codes.xsl

Any thoughts on what would cause this? I am not doing anything in the SQL db directly.

I had made a separate new parent portal on the DNN server, and then deleted it.

thanks for any help on this, tomvw

my problem with the timeout, as documented in the xml timeout thread in this forum, is apparently solved in version 4.7 and above, though I have not been able to test that yet.  Before that the host settings for this option did not persist in the db. It was in a bug report and supposedly fixed; hope it is and that someday when my non-core modules work on dnn 4.8.2, I can upgrade and make use of that. But with non-core modules, upgrading is not a simple process. Need to test them all first and that means finding time I don't have right now.

I will keep an eye on my xml module issue of losing the file settings, interesting that it does not seem to lose the URL remote xml settings, just the local static file ones.

Larry, no idea, at least not for DNN4.8.x. 

Just randomly guessing: Did you enable ajax for the XML settings module? If yes, disable it. What are your caching settings?   Disable caching for that module.Even then I never heared about a module setting that gets lost after days, weired.
