The issue is really strange. It seems that the Recycle bin module has not been properly installed and activated after the upgrade. What I can suggest is to go to Administration -> Modules and Services and scroll down the list of modules to check if the Recycle bin is marked as active. If it is not marked as active, you can install the module from its Actions link.
If the module is marked as active, please try to re-install the module following the steps below:
1. Backup you project files and the database
2. Please open the ~/App_Data/Sitefinity/Configuration/SystemConfig.config file and remove the version attribute of the Recycle bin module. The line should like below:
3. Then please change the build version of the SystemConfig.config
file to 2500
as shown in the text marked in yellow and save the file:
4. Please restart the application by resaving your web.config file and run your project in browser.
After opening the project in browser Sitefinity will run the upgrade scripts for the Recycle bin module and the module should be reinitialized again.
Please note that after making the changes to the SystemConfig.config file and then restart the application and run it in browser the Performance Optimization
page will appear. If this page appears, please press the Start optimization
button and wait until the process completes (please do not close or restart the browser while the optimization process is running).
We highly recommend to perform the above steps on a backup of your project
(not directly on your live environment since your site might become unresponsive during the optimization process and some issues may occur during this process). For example, you can create a copy of your project on your local environment and re-install the module on your local project.
In addition to this, can you please try to create for example a new page and then delete the page. After that please check if it will appear in the Recycle bin and please also open the sf_page_data
and check the value under the is_deleted column
for this page. The value should be 1 for the deleted pages.
If the value for the deleted page is 0, please delete the files under the ~/App_Data/Sitefinity/Logs folder (or copy the files to another location for backup) and then please delete a page. After that please check if there are any log files under the Logs folder and send the files to me to inspect them. The error log files may contain some additional information about the reason for the issue.
