*Problem* Server Error in Application

Hi,

I have a live website running version 2.50

Fresh install as of lastnight

I have managed to install SevenSpikes.Core from the install page in admin.

Then I uploaded the CategoriesHeaderMenu plugin to the plugin folder, as per instructions.

Then I go back into the admin page, click to reload the plugins and this error is thrown..

Source Error:

Please help me someone. Thanks

Hi,

Please make sure that the Core plugin is really installed.
To be 100% sure just check the InstalledPlugins.txt file and the Core plugin should be present there.
Also after installing the Core plugin you can try to modify your Global.asax file by simply putting an empty space in it.

Please let us know how it goes!

Hi,

Where can I find the installedplugins.txt file please?

You can find it here App_Data\InstalledPlugins.txt

Regards

Yes the core plugin is on that list of installed plugins and that text file was last modofied at the same time as me installing the core plugin.

I also tried the Global.asax thing but this has changed nothing.

I have managed to reload the other plugins in the list ok...

Ajax filters
Anywhere sliders
Cloud Zoom
Instant search

However when I click to install any of them I get this message at the top of the page in a red bar:

Access to the path '\\PDC2\sites\r\revohardware.com\public_html\Plugins\SevenSpikes.Nop.AjaxFilters\Settings.xml' is denied.

That error message was for AjaxFilters on that occasion.

Hi revotechnik,

In that case you need to set read\write permissions on the Plugins folder and all inner folders for the Network Service. The plugins folder has the right permissions but since you have added the new plugins they might not have the required permissions. Please set the permissions and try again and let us know if everything is ok.
If you still have problems please write to our support mail with login credentials to the web site and the ftp and we will assist you.

Hi,

So I changed the permissions and the already installed plugins have been configured and are now working great.

Still having the problem with the headermenu plugin though. I can now get it into the re-loaded list of plugins, so a step further than before. But then when I click install I get the errors.

Hi revotechnik,

It is good you have managed to install the other plugins but it is really strange why you can't install the Header menu plugin. Do you use the latest version of the Header Menu plugin? Please download the latest package and replace both the Core and the Header Menu plugin folders and then modify your Global.asax file as before. Then everything should be fine and please let us know how it goes.

Best Regards,

Hi,

I uploaded the core and headermenu plugin again, reload list of plugins, then this happens...
