I heard back from the tech support people at Houzz. Their advice for the IE browser problem: reset your browser by clearing history and cache then reopening. I will try that and let you know how it works after I manage to grab my computer son and get him to show me how to do that. : ) Thank you, bayarea_girl, for that info about Windows 10. I guess I might as well go ahead and add it to my computer. They keep sending me messages about it, but I've ignored them--out of sheer laziness. Didn't want to be bothered by having to learn how to use it. But it is evidently time. Out of curiosity, I'm trying the Houzz Photo button and see if it works for me. Hey, it works. OK--now I have two new ways to post pics. This is good! Thanks for that help, Sutekesh. (That is a pic of the mini-rose Sweet Diana, for the curious. ) Kate

I havent been able to post on houzz garden discussions for over a week now. Says Page not found when I try to log into gardenweb or houzz discussions. However, I can log and stay logged into the main Houzz portion of the website. I gave up after emailing to get help and trying a bunch if stuff. I am on the app now, which is a whole other can of worms lol.

Agreed KSWL. They bought what was once a thriving online community. Anyone who remembers Spike knows that there are pros and cons to various kinds of leadership styles. Anyone remember when they bought GW we got all kinds of platitudes about how they loved the GW "community" and they weren't going to change a thing? Little did I know that meant they'd also never update anything, fix anything, test anything, or communicate anything. Now we get to show up every day and just wonder what works/doesn't work - and if it doesn't work, good luck finding anyone who will even acknowledge your outreach. Sad face.
