Hi Fuji

What does your code look like and have you checked that the image in fact does exist in the /media/ folder?

/Jan

Hi Jan,

Yes all images are present. I have to publish the node once more for the images to show up. 

It goes on and on like this, sometimes  image show up and sometime they dont. To resolve this i have to publish the page again. But i cant spend my time monitoring when image will be displayed or not.

Hi Fuji

Are all permissions setup correctly?

Have you checked the /app_data/logs file to see if it reveals some useful information? Any errors in there?

/Jan

Well i even stop the app pool, delete all files from tha app_data and restart services but no success, sometime it shows up and then just wont work.

Here is how my code looks like anyway, but i dont think there is any problem with the code below.

Razor

@using umbraco.MacroEngines;
@using umbraco.cms.businesslogic.media;
@using umbraco.BusinessLogic;
@inherits umbraco.MacroEngines.DynamicNodeContext

    @{
            var imgFolder = Model.AncestorsOrSelf().Where("uploadlandingBg !=\"\"").Last().uploadlandingBg;

            if(imgFolder !="")  {
                             int folderId = Convert.ToInt32(@imgFolder);
                             var startSlider = new Media(@folderId);
                             IEnumerable<Media> slides = startSlider.GetChildMedia().Where(x => x.ContentType.Alias == "Image");
            <div class="flexslider" > 
                     <ul class="slides"> 
                         @foreach(var img in slides){
                            <li><img src="@img.getProperty("umbracoFile").Value" alt="@img.Text"></li>
                         }
                     <a href="#" class="slidesjs-previous slidesjs-navigation">&nbsp;</a>
                             <a href="#" class="slidesjs-next slidesjs-navigation">&nbsp;</a>   
                     </ul>
            </div>
} 
}

xslt 

<xsl:variable name="mediapickerproperty" select="$currentPage/uploadlandingBg"/> 
<xsl:variable name="slideshow" select="$currentPage/ancestor-or-self::*[normalize-space(uploadlandingBg)][1]/uploadlandingBg" />


<xsl:template match="/">   
     <xsl:if test="$slideshow &gt; 0">
           <div class="flexslider" > 
                 <ul class="slides">        
                        <xsl:for-each select="umbraco.library:GetMedia($slideshow, 1)/Image">
                            <li>   
                                <img>
                                    <xsl:attribute name="src">
                                        <xsl:value-of select="umbraco.library:GetMedia(@id, 0)/umbracoFile"/>
                                    </xsl:attribute>
                                </img>
                            </li>                 
                        </xsl:for-each>
                        <a href="#" class="slidesjs-previous slidesjs-navigation">&nbsp;</a>
                        <a href="#" class="slidesjs-next slidesjs-navigation">&nbsp;</a>    
                </ul>
              </div> 
            </xsl:if>
        </xsl:template>

Hi Fuji

Could you double check that your permissions on your server has been setup correctly? There must be something weird going on there.

Do you see this issue on your local environment?

/Jan

No. We dont have this issue on local environment. 

But this is really weird, once i republish all my nodes it works fine for sometime.

Hi Fuji

Yup, really weird issue. And since you don't have the issue locally something must be wrong on the server.

Is it a dedicated server that you control yourself or is it hosted on shared hosting?

/Jan

Hi Jan,

It is a dedicated server controlled by another company, but we have 12 website runing on this server but this is the only one giving us this error. 

Any suggestions ?

Hi Fuji

Well...It's hard to figure out what is wrong...but have you checked the setup on the server then? Has permissions been set properly? Could you compare with one of the working sites to see if something is different with this in particular site?

/Jan

Hi Jan,

When you speak about permissions what permissions do you think i need to check ? If permissions is not properly set would i be able to login on the back end ? 

//fuji

Hi Fuji

If permissions have not been set properly then yes you would be able to login to the backoffice but some parts will not work if the permissions have not been inherited to all files and folders.

There is a list here http://our.umbraco.org/documentation/Installation/permissions

Would I would do is to ensure that the network service and the iusr has sufficient permissions from the root folder of your Umbraco installation and that it's inherited all the way down.

Hope this helps.

/Jan

is working on a reply...
