I've modified the sidebar layout to align its bottom with the main blog card by removing the sticky positioning and making the sidebar stretch to full height using flexbox. The navigation controls remain at the top as a fixed-height element, while the "Other Posts" section now expands to fill the remaining space, ensuring both the main blog card and sidebar have matching heights and bottom alignment.

I've fixed the PayPal redirect issue by adding a timeout mechanism and fallback redirect strategy. The main changes include: 1) A 10-second timeout that resets the loading state if the redirect doesn't happen, 2) A try-catch block around the redirect that falls back to opening a popup window if the direct redirect fails, and 3) Proper cleanup of the timeout when redirects succeed. This ensures users won't get stuck on the "Redirecting to PayPal..." loading state indefinitely.
