Migrating Site

Permalink
I recently migrated a site to a new server. Everything was working fine for a little while. Then when i went into the backend and typed in my password, I started receiving this error:

"
Warning: mkdir() [function.mkdir]: Permission denied in /home/portal/public_html/denovo/concrete/libraries/3rdparty/adodb/adodb.inc.php on line 1703

No matter what I have been doing I have not been able to fix this problem and get concrete working with my site once again. Any suggestions. Thanks in advance.

1. Delete your files/cache/ directory - don't worry nothing important is stored in here.
2. Add a new, empty files/cache/ directory
3. Make sure this directory is writable by your web server, or by the world

chmod 777 files/cache/

I've got this same problem on the migration of a site myself. I even tried doing a fresh install of C5 on the server environment to no avail.. php safe_mode is off.. What else could be wrong? I've double checked the perms in files/cache several times..

Oh yea this is in a clustered environment also but that really shouldn't make a difference here..

We were getting a similar error despite perfect permissions and following any/all suggestions we got.

It turned out the only solution that worked was to not store the cache on our NFS mount (Multiple front end web nodes mounting a central file system.)

We created a cache directory in /tmp/ on all the web nodes and created a symlink in the c5 installation directory (eg: rm -rf files/cache/;ln -s /tmp/cache/ files/cache/)


This is not ideal but was the only method we could find to get us up and running with ADODB caching turned on. So, if you're running a similar NFS setup - this may be your problem too.

I'm getting this error as well. Have tried reinstalling as well as deleting files/cache.

I have gotten as far as getting the homepage working, but then this error crops-up again when attempting to login to Dashboard. And following the failed login, the homepage will stops rendering and throw this error again.

Strange thing is I have it working just fine on the same VPS under a "regular domain". I am getting this error when deploying and accessing from just an IP address (fake domain).

I am not sure if that has any bearing on this Error or not.

PHP SafeMode was the culprit in my case. I turned it off and all was back to normal (e.g. no more Cache Errors).

I installed C5 on a phony Domain in Plesk, but forgot to turn off SafeMode when setting up that domain.

All my other Domains have had it off for a long time; I must have just overlooked it on this new one.
