Code Editor Fails on vanilla install

    I’ve seen a bunch of complaints about the new code editors refusing to save edits, and displaying the following message:

    “Unable to communicate back with site to check for fatal errors, so the PHP change was reverted.”

    Every topic I read seemed to indicate that the issue was plug-in compatibility. However, I’m seeing this on a vanilla install, with no plug-ins installed (not even Hello Dolly or Akismet).

    We have a handful of existing sites which we’ve upgraded to 4.9.x, and the editors work fine (well, they overstep IMO, but they’re functioning as expected, not desired), but on this one new site without anything – not even a new page or post loaded – the editor fails.

    Are existing bug reports addressing this, or am I looking at something new and different here?

    I don’t know of any such issues but have you tried another browsers to see if you can replicate the problem?

    Although I do not know if this is the case for you but anytime I do a install I would do a compare of my installed files versus the core files. I would install WordFence plugin and run a scan. The results should show it’s clean but rarely I get one of those times I have a corrupted or missing file.

    I hope this helps.

    Thanks for the reply. I just tried reinstalling 4.9.1 in case there was a corrupted file, and that didn’t seem to solve the issue. I also installed and checked WordPress Health Check. I didn’t believe there was a problem associated with the account/server settings, but I checked just in case. The core files are clean, the system is healthy, there are no plug-ins, there are no new pages/posts (which shouldn’t matter), and even the theme is basically an empty shell, with a few basic functions also found in Twenty Sixteen. I’m perplexed.

    Please install the health check plugin and report back its findings: https://ww.wp.xz.cn/plugins/health-check/

    Also try the button on the troubleshooting tab that lets you disable all plugins to see if this issue is plugin related.

    EDIT: oops… i see you did that already. hmmm…..

    I would suggest find another computer or fried to login via admin and see if the problem is the same elsewhere. You might even ask your host to do it.

    Again, I never experience this problem on any version of WP.

    Maybe someone else will chime in.

    I would do that, except I have none installed 😉

    I figured out the problem! We still have the default search form code in the searchform.php page, and this code has a function that attempts to call an SVG image. I didn’t clear out that code, and as a result, it’s borking the entire editor. Once I removed it, the code editor came back to life.

    tkgnewseed – switching browsers worked, sort of. Firefox gave me a stack trace back to the issue that was being suppressed by Chrome. That’s where I spotted the error, and now it’s fixed.

    That’s a really horrible way for an editor to break, off an entirely unrelated page elsewhere in the theme. Just…wow.

    If you’re really up for some fun, install Gutenberg via plugin and see if it has the same issue. If so, let the Gutenberg devs know, either on the plugin’s support page or on Github.

    Spoke too soon. The issue is resolved, but it’s not related to that search form issue. Apparently, the editor makes a remote call of some kind (not sure what – I’m too tired to trace it through the network), and because we’re blocking the public from viewing the site unless they cookie in first, the editor is blocked. I put together a script that looks for a cookie you set by visiting the domain using a specific query string. This way, the public sees a blank page, but someone with the correct link is cookied in and can see the site.

    Apparently, this does not play nice with the new editor. Once I set the cookie (it’s only necessary for the front end, not the admin dashboard), the editor stopped messing up.

    The good news is that this particular issue is limited to just me, and it’s resolved. The bad(ish) news is that it makes me wonder what else might make the editor go sideways like that – htaccess on a domain? Some other method of view control?

    Either way, we’re good now! It’s NOT the search form – it was a cookie issue.
