Hmmm. But what did we change to make that happen? i.e. Why does https://atlantic-computing.com/forums/viewtopic.php?t=7 no longer produce a blank page as it did before?
Still a blank page here. :?
Works OK for me.

Browser cache problem?

Nope, browser cache is always emptied upon closing browser. Plus: tried with FF, Chrome, Edge and Opera.

Something that I have just noticed, and I have no idea whether it has any bearing on the current problem, is that around the time that this problem started the was a possible bot attack on the board - it had its highest number of visitors. Without any disrespect I doubt that this board is one that would attract a lot of simultaneous visitors from a search.

Searching for this error SoftException in Application.cpp:630doesn't have many results or any solutions. As David noted you had a lot of activity and one suggestion I did come across was it's caused by MySQL refusing connection because the connections are maxed. Have your host check the MySQL error log.

If you check that activity in access log it's likely a lot of Chinese IP's.

For what it's worth: I can now access topics. (so david63's observation is certainly worth taking into account).

Ladies and gentlemen,

The latest update in our continuing saga.

First of all, before beginning, a sincere thank you to all of you for your assistance. Your technical advice has been invaluable.

I received the following to an unexpected email address, which apparently is what my hosting company has on file for me:

Thank you for contacting Bluehost! I'm the technical representative who looked into the case #23998832 regarding website functionality. I understand it is important for you to have your website working without any issues. Sometimes, the intensity of the issue involves a lot of troubleshooting and this impacts our promptness. Thanks for being patient with us.

Upon reviewing your website https://atlantic-computing.com/ pages, I was able to replicate the issue with pages loading blank and receiving 500 server error. I've further investigate on the error received and noticed that the issue was causing due to .htaccess code and PHP version of your website. I've renamed the .htaccess file and added PHP handler code in order to fix the issue. Also, set the PHP version to 7.2 which looks to be needed to meet the compatibility of your Version of PHPBB and its functions. Now your website and its pages when accessed are loading fine without any blank screen or error message. Here is the screenshot of the same:
{screenshot is included here}

Additionally, Please access your website in an incognito window or a private browser to negate the cache effect on your website. Here is the link to know about how to clear browsers cache: {directions included here; message concludes}

In fact, .htaccess was replaced, which fixed the PHP but broke secure http for the entire webpage overall. One of my employees is working on that now and I think that is fixed. php.ini and user.ini were also modified in the fix - we haven't touched those.

Test accounts have been placed in the proper groups and passwords have been updated, so forums and topics are visible to all in the proper manner.

Still borked at this time:
1. New Topic returns a blank page
2. Any replies to a topic also seem to produce a blank page. My employee was able to post one reply on mobile phone browser very early this morning, but we cannot replicate this; looking at timestamps, this may have been done in the middle of my hosting company's efforts.
3. Intermittent blank pages being returned clicking on tabs in the ACP. For example, clicking on Maintenance from General returns a blank page; clicking on System from General and then clicking on Maintenance brings up the tabs normally.
4. Private Messages returns a blank page
5. Your Posts from the Quick Links menu is also a blank page

I'll be putting these in an email back to the hosting company shortly. I'm also checking the rest of my website for functionality; parts of it (not the forums in particular) will need to be working for later tonight.

Just accessed your website now (as guest) and clicked about 10 topics, also went to last posts in topics from the index.
No problems at all.

I noticed that as well. It did occur and conclude before the problems started, so I don't think it was a direct cause. This behavior occurred several times in the past and was related to a spike in bot/spider activity. I had tried a couple of different fixes, such as banning bots outright or grouping them in the Bots group which I then very heavily restricted, but nothing seemed to stop the occasional weird spike in the visitor count. It didn't seem to affect any functionality so I put that on the backburner as something to look into later.

Nope. You should use .htaccess to redirect http:// to https://
and the cookiedomain is back to domain=atlantic-computing.com?

Did they rename the old .htaccess like they said, and when you look at that old one does it make sense why "the issue was causing due to .htaccess code"? If you have that prior/renamed one to post here in some [code][/code] tags, it would mostly just be for curiosity. And presuming there is nothing sensitive in there for you.

You may be thinking the same, but I'm not sure their throwing "PHP 7.2" in there was actually a necessary part of the solution. They might have thought phpBB 3.3.0 wasn't compatible with PHP 7.3, but that's not the case. Whatever else they "removed" by replacing your .htaccess, if anything, seems like that must have been the main issue.

I agree that when checking the site right now, although the redirect for http://atlantic-computing.com/ to HTTPS worked, the was no redirect for http://atlantic-computing.com/forums/. Which in a way is strange, since it means the redirect rule in http://atlantic-computing.com/ was crafted to not apply to URLs which contained a non-empty path? In most cases, the redirect at the http://atlantic-computing.com/ level would have already handled both cases / any path the visitor was attempting to access on that site.

Yes, I switched that back. My mistake; I had thought it was necessary for access. I will switch it again shortly.

Okay, I have asked my employee to review, and she has discovered the .htaccess in /forums. Reviewing that now.

Changing that seems to have made no difference. Delete cookies afterwards still produces an AJAX ERROR: Internal Server Error
