cache folders cause file synch errors

Hi, John,

I just upgraded to DNN 4.5.3 and have the latest free PageBlaster installed.

Whenever I do a recursive re-synch of the filesystem with the scheduler, I get errors about inserting null into the lastupdated column of folders. After lots of trial and error, I have discovered that the folders under the cache folder in the _default portal are the problem. When I delete all of these folders on the physical file system and do a recursive resynch at the cache folder, no errors, and also I can schedule a file synch and it works with no errors. That is as it should be because I have spent a lot of time investigating files/folders tables and physical. Lots of time.

But after I navigate around on one of the DNN sites and a folder with that portal name is created under cache, then the file synch errors resume, both in filemanager and in scheduler.

I assume that I must have something not set correctly either in PageBlaster config or DNN somehow.

I'm not using DNN compression at all, nor whitespacefilter; I have Page State set to Page, and module set to Memory; Moderate caching, and "ServerAndNoCache."

In DNN, the "cache" folder IsProtected is true ( =1 in folders table). Not sure if that is relevant.

Can you advise me on how to deal with this?

Thanks,

Mike

OK, thanks. Have done so but don't see the new folders getting created there now.

        cache-folder="/Cache"
        config-folder="/portals/_default/Cache"

the config file is also in the DNN root ... should it be like this?

        cache-folder="/Cache"
        config-folder="/"

The config folder doesn't really matter on the free version, so you may want to set it the same as the cache folder.

Check to make sure that you have write permissions set on your Cache folder.

Showing up now for one of the portals, just not the first one.

Thanks for your help!

Mike

Dear John

When I saw this thread in the dnn-forum this morning, I thought I have to look at the Log viewer of a few of my sites.
And what did I see?

What did I see at the cache folders of this site /Portals/_default/Cache/tabid.
(Snapsis ΐ.2.4] free version installed)
Different folders are created... 101 102 103 ...
In the folders nothing...

May I ask you: Is the solution for that what pmichael has said in the thread of dnn?
Or, is there something else to do?

Hi Gilbert,

I don't the errors are related. Your's appears to be caused by trying to cache pages in the providers folder for FCK editor. 

I would put an excludePath in for any url with FCK in it.

Hi John

I think I don't understand you completely...
You said: Your's appears to be caused by trying to cache pages in the providers folder for FCK editor.
I use the Fckeditor as html/text editor.
I don't have a page with the name FCK in it...
Perhaps when I use the FckEditor then he looks like a page like FCKCSS.aspx, Fcdkeditor.html... and then perhaps he try to cache this page and give this error... Then of course I have to put an excludePath for any url with FCK in it.
If that is correct, then it isn't only by me?...

But what did I see also...
I see the tabs in the folder of the cache pages (..._default/Cache/tabs...) and they are empty... Is that normal?...

Hi John

This is the Snapsis.PageBlaster.config file that I use. As you can see these are the normal setting that you set...

As you can see ..._default/Cache is indeed set in Snapsis.PageBlaster.config file. And fck is excluded...

What do you mean with
'do you have a non-zero interval for disk-cache-interval? If so, then your disk caching may not be working.'
The disk-cache-interval is set to "01:00:00:00" that means indeed non-zero... and then you said: my disk caching may not be working?... 

I think that I've full permission on that folder... I will check it...
But when dnn create tab folders in the ..._default/Cache folder then it is normal I think that I've write permissions... Or am I wrong?

Hi John

I've checked site 1
One with the General Exception as I mentioned...

There are about 50 tabId folders created in the ".../portals/_default/Cache folder.
All the folders are empty...
One .pb.webinfo file in the ".../portals/_default/Cache folder.

I've checked site 2

Also about 50 tabId folders created in the .../portals/_default/Cache folder
A few folders empty
One .pb.webinfo... file in the ".../portals/_default/Cache folder.
Different folders with one or more .pb.webinfo... file

I just had a thought ... this is probably not related to what you folks are discussing now ... but if there were a placeholder.txt in each of the files at /Portals/_default/Cache/{portalname} along with the ....webinfo files, then the DNN file synchronization would probably work ok.

As far as I am concerned I'm good with the /Cache folder at the root, but it might simplify installation for some users to continue to use the _default/Cache folder ... and I am thinking that a synchronizable file such as placeholder.txt would make that possible.
