>> Hi!
>>
>> where i have to look for the solution to such problem:
>>
>> after login I get an empty frame on the left side of browser window  
>>  where the sidebar should be shown. There are no icon also shown   
>> which helps to hide and show sidebar. Sometimes, after some   
>> operations sidebar frame disappers completely and not shows up   
>> during session.
>>
>> It is possible to turn on sidemenu in dimp and then there are two   
>> "sidebars" - one - empty and one - provided by dimp.
>>
>> On my ancient webmail installation everything goes on smoothly, but  
>>  on the webmail 1.2.4 and 1.2.5 I can't figure out what's wrong or   
>> how could i disable sidemenu at all not to bother with.
>
> Most likely you have a fatal error somewhere that is preventing the
> sidebar from showing. Check your webserver error log to find out where
> the error is occurring.
