Wondering if there is still help for a friend’s very old concrete5 install?
concrete5 Version 5.6.4.0
PHP 7.1.33
When we log in, there is nothing in the bar above web pages to allow editing, dashboard, etc. Just a blank bar. Thus, no way to edit existing pages. Help?
EDIT:
This message shows in error_log for every page viewed:
[28-Dec-2025 17:53:09 UTC] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/accountName/public_html/updates/concrete5.6.4.0/concrete/tools/page_controls_menu_js.php:4) in /home/accountName/public_html/updates/concrete5.6.4.0/concrete/core/libraries/view.php on line 648
End of edit
I also see error messages here and there such as:
“An unexpected error occurred. Call to undefined function simplexml_load_string()”
when I click the “News” link in dashboard.
and, when I click "Page Properties" in Dashboard/Sitemap:
”Warning: Cannot modify header information - headers already sent by (output started at /home/accountName/public_html/updates/concrete5.6.4.0/concrete/tools/edit_collection_popup.php:99) in /home/accountName/public_html/updates/concrete5.6.4.0/concrete/core/libraries/view.php on line 648”
”An unexpected error occurred. Call to undefined function simplexml_load_file()”
I tried going to other versions of PHP. Higher version and some pages, or the whole system, do not work. Lower PHP version does not help my issue.
Any ideas beside creating a new, up to date, website?
Thank you!
