Falcon Engine crashing my site

  • Yesterday afternoon I finally had the bulk of what I wanted done on my site and decided to enable the Falcon Engine to see how it would improve my speeds.

    It was shortly before leaving work. Today when I came in I had the following as my website.

    https://www.cmslaser.com/wp-content/uploads/2014/09/2014-09-23-08_41_53-www.cmslaser.com_.jpg

    I called my host’s support and started a backup from the day before. That didn’t solve it (because the backup had the Falcon Engine change. I went back one more day and all was well.

    I figured something had glitched in the code as I have Wordfence and IThemes Security guarding my side, and my CDN also watching for attacks. I began updating all the changes I’d made Monday and everything was looking great.

    I eventually got around to the Falcon Engine, changed that, and went on to a video gallery plugin I’d installed. And…crash. The same thing happened.

    I was suspicious of the video gallery, and rather than do a restore, I disabled all my plugins. I added back ones I knew had worked for months, and the bare minimum to make my site work for the client.

    After that stayed up and solid for an hour, I began adding back the remaining plugins one at a time. I left the video gallery one for last, and never made it back to it. I went to change to the Falcon Engine and the site went right back to that lovely “Riddler” screen as my boss so unaffectionately calls it.

    He was quite happy to see the site down the first two times so I was praying that disabling the Falcon Engine would bring things right back before he noticed. Hallelujah! That did it. Right back and it’s stayed back.

    So…not sure what’s going on, but Bluehost had never seen it, I’ve never seen it and I haven’t seen any other support requests for it. I hope you know what it is!

  • Yeah Try disabling the gzip in the w3cache and see if same thing happens. Let me know.

    here’s my system’s configuration as generated by wordfence, if that helps.

    i can’t test disabling the gzip until later this evening…at least sometime after 6 pm pst.

    let me put the sum of what i’m running, or not, at any given time, and what causes the problem all in one place.

    my site runs about 25 plugins at this time. prior to this wingding unicode issue, the only problem i’d ever had is the All In One SEO program somehow causing occasional 404 errors on pages that were valid. It took some digging through my error log to start narrowing that down, but once the trail was sniffed, it did lead me to that plugin, and disabling (and deleting) it solved that.

    wordfence had been installed as a security plugin, along with ithemes security for about 6 weeks. while digging on the AIO SEO program, i decided to dump ithemes security, too, and just go with wordfence. so…wordfence was the only security plugin running on the site for about 2 weeks. it does security in conjunction with our CDN company (incapsula) and i’ve been pleased with the results.

    while looking through wordfence one day, i ran across the Performance Setup again, which i’d seen when installing but had left alone while getting all the bugs out of the site. i decided to turn on the Falcon Engine at that time. no other caching plugins were present at that time. the site went down, unbeknownst to me as i did that just before leaving work.

    the next morning, the solving and return of the problem led me to the Falcon Engine and we left it off. as wordfence states that the Falcon Engine will not work in conjunction with W3 Cache, i decided to try that plugin with the performance part of wordfence turned off. it brought the same result.

    i disabled W3 and we left that alone for the remainder of the day yesterday. this morning, from home, i set wordfence to basic caching to see if that worked. i saw nothing improper in the half hour before i left for work. after an hour drive, and approximately a half hour into my work day (2 hours from the change) the problem was back, fixed by removing the basic cache setting.

    the StackExchange link posted by Tim above seems to have plenty of evidence (or as much as i can find anywhere about this problem) pointing to cache plugins and specifically to gzip issues. i am not anywhere near versed enough in the complexities of how gzip works, how the headers are created or passed to browsers, or anything like that. it just seems to me that this might actually be the problem.

    i’m going to have to test w3 cache this weekend. there are too many settings to try one at a time. i’ll just disable them all and then bring them back one at a time until it crashes again.

    i just tried disabling gzip and that didn’t seem to do anything. i’m wondering now if it could be minifying js/css twice. but…i’ll work on it this weekend.

    i installed wordfence on my personal website, hosted in the UK, and have had no issues with running the Falcon Engine there. here is a link to that server configuration. perhaps someone who knows more than i can compare it to the one above from our Bluehost server and see if anything can be identified as a cause there.

    Sorry but I tried that link I asked for again and no luck. You’re probably seeing it because you’re signed in as admin.

    not sure why that would be. it’s just a direct link to the file on my server.

    it looks pretty much exactly like the photo at the top of this forum page.

    https://wordpress.stackexchange.com/questions/59309/page-output-in-strange-characters

    if i look at the page source code, it looks the same…no change. i am reading more about improper encoding being sent being a reason for random unicode characters being inserted into otherwise normal text. i don’t know if something is changing the encoding completely through all the mess that’s leaving me with that page.

    over the weekend i was able to get w3 cache to work on the site…or part of it. i have object, browser, and database cache enabled. next weekend i’ll look at enabling page cache, as well.

    i left minify and page disabled for now. i already was running a minify plugin before i added w3 so i decided to leave it at that.

    i’d hoped to test all the way through w3, but we had a 404 error anomaly that was affecting only one part of our website. i had to put most of my time into that.

    still, some caching > no caching.

    Amen to that. And I get the busy stuff. Some times I get working through an issue only to — SQUIRREL! — wait a sec…what was I saying?

    Anyway, the site is up and cached, and wordfence is working. You’re getting there!
