weight loss plateau now gaining

Man, there's a lot to unpack here.

After 3 weeks of the plateau I decided to switch to maintenence (using mfp calculator) of 2150kcals /day. I started slowly gaining weight just in 2 weeks. I admit I did overdo it on one weekend, (ate 3000kcals on sat and sun) but that was just 2 days and I went from 78.3kg to 79kg (that's a weeks worth of weight loss for 2 days) .
So am I right to think that I need to stick to a maximum of 1500kcals just to maintain?

First, you tossed out a lot of individual daily numbers. I always use my average calorie intake over at least 2 weeks to make any kind of conclusion. I would suggest you do the same. My calories, like yours, over that 2 week period spike on the weekends when I have a few beers and usually eat more calories. I have no trouble losing weight with this kind of volatile calorie intake but I make sure my average for the week is within reason. That means I'm under budget some days and over others.

Also, if you go from under-eating for a long time to a much higher calorie intake it's normal to pick up some extra weight due to higher volume of food and water in your body. I would wait for it to stabilize before drawing conclusions. As a 39 year old male weighing 171 lbs you should be able to maintain your weight eating (on average) around that 2150 number -- because that sounds like a sedentary number (even though you didn't give us your height). Your number might be lower now because of a long time period of undereating where your body has made adjustments to conserve energy. If you refeed as suggested above you hopefully can get back to a normal. I want to emphasize the average part of this equation. You can't eat a maintenance Sun - Thursday and overeat Friday and Saturday. You need to maintain an average calorie intake (including those over days on the weekend). That means eating below 2150 during the week to save up for some overage on the weekend. Whether or not 2150 is YOUR number depends -- but it's certainly not 1500. You'll have to experiment and draw conclusions based on averages over a couple of weeks to find YOUR number.

I can't go boxing or jujitsu because of the virus so my main cardio is dead. Do I have to go back to 3 heavy weight training session a week? Cos honestly I hate that.
I'm Pissed off sorry to moan but I have no one to ask about this stuff.

This is an entire thread on its own. I always tell people never do anything to lose weight that your aren't willing to do long term to maintain it. I love lifting. If you don't then find something else -- it doesn't matter what but just sitting around all day isn't healthy -- regardless of weight loss or gain.

Thank everyone. I guess I'll stick to the higher numbers as an average over the week as suggested and see what happens in the month. I didn't mention my height, I'm 5'11".

Obviously I'm no expert, but 0.7kg up in water weight alone seemed like a lot

I went from 124.8 pounds (56.6kg) to126.2 (57.2kg) pounds from one morning weigh-in to the next, from eating about 650 calories above normal goal. That's 1.4 pounds, about .64kg, but I'm 5'5" so quite a bit shorter as well as lighter. I've had bigger jumps, that's just a recent one.

I've been calorie counting for almost 6 years. This is not even remotely unusual, and occasionally happens even without exceeding normal calories. (Following day, I was back down to 124.6 lb (56.5kg) again.)

On a 5'11" body, 0.7kg seems pretty normal . . . maybe high normal, but normal.
