-        - 🔍 **Search first:** Before submitting, check if the issue has already been reported or resolved in [closed issues](https://github.com/community-scripts/ProxmoxVE/issues?q=is%3Aissue+is%3Aclosed). If found, comment on that issue instead of creating a new one.  
-        Alternatively, check the **[Discussions](https://github.com/community-scripts/ProxmoxVE/discussions)** under the *"Announcement"* or *"Guide"* categories for relevant information.  
-        - 🔎 If you encounter `[ERROR] in line 23: exit code *: while executing command "$@" > /dev/null 2>&1`, rerun the script with verbose mode before submitting the issue.  
-        - 📜 **Read the script:** Familiarize yourself with the script's content and its purpose. This will help you understand the issue better and provide more relevant information
+        ## ⚠️ **IMPORTANT - READ FIRST**
 
-        Thank you for taking the time to report an issue! Please provide as much detail as possible to help us address the problem efficiently.  
+        **1. Reproduce the issue with verbose mode - this is mandatory.**
+        Set `var_verbose=yes` (or *Advanced Settings → Verbose Mode*) and run the script again.
+        Only a verbose log shows what actually failed - a bare `[ERROR] in line 23: exit code *` tells us nothing.
+        **Reports without a verbose log will most likely be closed.**
+
+        **2. Search before you post.**
+        Check the [closed issues](https://github.com/community-scripts/ProxmoxVE/issues?q=is%3Aissue+is%3Aclosed) and the [Discussions](https://github.com/community-scripts/ProxmoxVE/discussions) (*Announcement* / *Guide*). If it is already known, comment there instead of opening a new issue.
+
+        **3. Read the script.**
+        Knowing what it does makes it much easier to describe the problem - and often to solve it yourself.
