Parts of website not shown – problem aggravated

Dear Ismael,

Thank you for reply and update to the staging site. The staging site is indeed working again as it should. I checked FF, Explorer and Chrome.

However it raises an obvious question: why does the live site not have this problem although it had the same header.php? Clearly it is a combination of factors of which (at least for me) one other factor is unknown.

Some other observations:

• Today on both the live and the staging site it says that there are 2 updates available and 1 plugin update. When I check: no update is actually showing. (I had a similar problem before but that was resolved with entering the Envato private token). However, as this issue is the same for both sites is is likely to be not related.
• On the live site the ‘All in One SEO’ option is shown in the menu right under ‘Dashboard’ but it is missing on the staging site, although the plugin is installed on both sites. As this is a difference between both sites, it might be related.

Also please note that the malfunction was different: only Explorer affected verses all browsers affected.

So in other words:
1. What causes the difference in behaviour between both the live and the staging site?
2. Why is the ‘All in One SEO’ option not shown anymore? (possibly induced by the change to header.php?)

Best regards,

Jan

Hi Ismael,

I have not made any changes to header.php. I also checked the header.php file from the live site versus a back-up from July 24 of the staging site and I see no difference. However, strangely enough if I restore the header.php from this back-up I am not able to reproduce the error.

I noticed 4 changes in the header.php:

• the line commented out <!– <meta name=”theme-color” …. was removed
• onload=”preloader()” was removed from the body tag
• php script “/** *WP 5.2 add a new function – stay backwa…” was added
• php closing tag “?>” was removed.

I assume all these changes were made by you. Am I correct?

There is a differences though in the functions.php: between staging and live site. On the staging site I used a script (from this site) to check for plugin update errors. I don’t see how this can be related, but I just mention it FYI. (Please note that I included the functions.php file in the check to reproduce the error).

I also noticed that in the functions.php the line “wp_register_style ….” was commented out, which I assume you did just prior to changing the header.php. Is my assumption correct?

Furthermore, I noticed that on the home page of the staging site a <br> tag went missing most likely in the process of restoring the staging site from a back-up as part of trouble shooting this whole issue. I noticed a similar issue with an other site lately on the same server, so I start to doubt the integrity of Installatron.

So because I can not reproduce the situation and because I have to put a question mark on the back-up/restore/clone process of Installatron, I think there it is no use to further pursue this issue.

Or.. how do you see it?

So I would like to know if you did indeed make the changes as I describe here (to rule out any other “interference”) but apart from that I think we better stop this thread unless you have a new and fresh idea about this situation

Best regards,

Jan

Hi Ismael,

Sorry for the late reply. The situation is kind of strange, but it is very hard to trace everything back.
Main thing is that the initial problem (some elements not been shown) is solved.
So yes, please, close the thread

Best regards,

Jan
