I have cleared out my cache and rebooted my laptop several times without any improvement. The problem is arising when using either Chrome (my preferred browser) or Firefox for me as well. I've done a bit of experimenting this morning and have isolated one thing that may be causing the problem.
1. I entered a recipe and, for the "Source" field, selected an option from the drop-down list of previously entered sources. I then added some information in the "Notes" field and clicked the "Save and New" button. The wheel spun for three minutes and then the "Error! Something's gone wrong here message" appeared. I then clicked on the link in the error message to return to the previous page. What appeared was an input screen for a personal recipe with no information except the source and notes data I had entered. When I checked under the "Recipes" tab, the new recipe wasn't there. I then exited EYB and opened the site again. Lo and behold, the complete new recipe was in my "Recipes" tab.
I repeated this exact same sequence twice and had the same results. In each case, it took three minutes for the error message to appear.
2. I then entered a recipe and entered the source manually, even though it was available in the drop-down list. I also added note information before clicking "Save and New." The recipe was updated instantly. I repeated this sequence two more times and had no issues at all.
So the problem seems to be arising from using the "Source" field drop-down list. Vanessa, could you be doing the same thing when you've had issues?
It's easy enough to manually enter the source although it does slow me down when entering recipes. I'm a bit perplexed about why this is happening now as I've added over 6,100 personal recipes to my account and have used the source drop-down list extensively to assure consistency between entries as well as for speed of entry.
