Advanced Traffic Statistics: From Insight to Active Defense 1.8.3

This update focuses on data accuracy and improved visualization for traffic analysis.

• Critical Chart Time-zone Fix: Resolved an issue where the daily chart was showing a one-day offset due to server time-zone differences. The data displayed in the "Last 30 Days" chart is now perfectly aligned with your database records.
• Improved Bot Tracking & Visualization: The Daily Chart now features a dual-line display: one solid line for unique human visitors and a new dashed line specifically for Bot/Crawler activity. This allows administrators to immediately distinguish between real user peaks and search engine crawling spikes.
• Widget & Report Synchronization: Fine-tuned the counting logic to ensure that "Live" data in the report matches the "Real-time" sidebar widget perfectly.

After uploading the files, please complete the upgrade process in your Admin Control Panel.

• [NEW] Bot Historical Tracking: Added database support (totale_bots column) to store historical bot traffic separately from humans.
• [NEW] Dual-Line Graph: The "Last 30 Days" chart now plots a secondary red dotted line for Bots, allowing for better traffic analysis.
• [FIX] Counter Logic: Fixed a calculation error where today's visits were sometimes summed twice in Monthly/Yearly totals.
• [FIX] Sparkline: Fixed an issue where the sidebar mini-graph displayed duplicate bars for the current day.
• [FIX] Database Schema: Improved installation/upgrade routine to ensure all necessary columns are present.
