CMS Made Simple Forums

Its absolutely no meaning to make a comaparison chart! Its only the two latest versions that are supported anyway - so yo have no reason to comapare them...
Realy read the changelogs and you see why!

probably not enough mem for php.
Try to install one of the small ones...........

wrong user permissions for the db...........

We have users on CMSMS that have some thousand  of pages running.
Currently the limiter for many pages are for the expand and collapse of the page tree on the listcontent in admin.

@Jeremy Gasowski Answer in summarium: set memory_limit: 64M          since 18M is to low for CMSMS and most other CMS'es. and also consider to set upload_max_filesize: 10M for future trouble safe uploads / upgrades. And upgrade to latest core(1.8.2) since some issues is fixed there... -topic locked-

ops
almost forgot to reserve my seat at Workshop...
.... I'm fine now  thx   

if you can acces admin - run the System verification test.

If not - try uploading all files again and be sure to overwrite all.

or if you add
error_reporting = E_ALL & ~E_DEPRECATED
to the active php.ini ()wamp have many of them - one for each php version)
it should be working after a service restart.

I come - as always! 
This will be realy be interesting!
I look forward to attend a workshop also...

I think an export function or something are worked on...
But don't know when this can be ready since all devs on this modules is swamped in work lately 

(I won't / can't upgrade FB/FBr myself on some sites because of this)

NCleanGrey is both front and back theme...

All themes in admin/themes are for admin area only.
Themes for frontend that you install with ThemeManager are usually ending in uploads/NameOFTheme/.......

I guess its some manual job to migrate...  But you can probably use a tool to create the page hierarchy for CMS Made Simple to make the page hierarchy so similar to your current as you can.
After that its probably some hours worth of copy-paste.

probably files not loaded up correct  or  wrong permissions on folders and or files

be sure that
  correct_name
is the name of the stylesheet, Its case sensitive
{cms_stylesheet name="correct_name"} 

more info please....

errors in php error log?
all ok in system information?
etc
