We have a page with 13'000 nodes.
Sometimes on our staging environment the Multi-Node Tree Pickers doesn't display any nodes anymore. We found no way the get the nodes back - we always have to restore the whole instance from the productive system.
It looks like the systems loses some indexes. Is there a way to recreate the whole site index? (Republish the entire site and deleting the umbraco.config-file doesn’t work)Thx for your support!
Do you get any errors in the log?
Only "Domain already exists in list (*)"
I'm not sure this is related to 'Indexes' (which is referring to Lucene/Examine)?
By this "Sometimes on our staging environment the Multi-Node Tree Pickers doesn't display any nodes anymore" do you mean in the back office?
You can rebuild the cache file by deleting the umbraco.config file and then restarting your app (bump web.config).
You can rebuild all Examine indexes by deleting the folder ~/App_Data/TEMP/ExamineIndexes and restarting your app - this will rebuild all indexes during startup.
Same behaviour when I deleted the umbraco.config and restarted pool.
After I deleted the ExamineIndexes and restarted the app - I get the following error when I save a node:

Remark: The "Link to document" displays following error message: "Oops: this document is published but is not in the cache (internal error)"
And yes: The problem is in the back office but without any js errors.
What version are you using
umbraco v 4.11.5
I've seen that op_Explicit error before, it's to do with the content xml not containing the correct values. Here's a query with that text on our issue tracker:
Would be worth reading through those to see if any of those fixes relate to you.
