Site fails after upograding to PHP 7.4 Topic is solved

[ArtistScope]

After updating PHP from 7.2 to 7.4 my Joomla site now hows "error" on a white page.

I have searched the forum and checked XML libraries, etc and still solution. SimpleXML is installed as seems everything else. But I still get these error...

Code: Select all

I even tried a fresh install and still got...

What could be the cause?

[AMurray]

It could be extension or template incompatibility. Or some required PHP 7.4 functionality is not enabled when it was in 7.2.

We can discover what might be wrong with additional information: please run the FPA and post the report results to the forum; follow instructions found here: https://forumpostassistant.github.io/docs/

It is curious though, that you have the same issue with a fresh bare-bones installation? Latest Joomla 3.9.x will work on PHP 7.4.

First thing that I noticed is that it reports SimpleXML or allow_url_fopen not available, yet isn't SimpleXML part of PHP-XML which is installed?

PHP 7.4 cannot be used with J! 3.8.7.

/end

[ArtistScope]

Did you notice that earlier I mentioned that I tried a fresh install using the latest version and from /installation/index.php I still got...

Code: Select all

Deprecated: Array and string offset access syntax with curly braces is deprecated in /var/www/html/joomla.artistscope.com/libraries/joomla/filesystem/path.php on line 149
Error: Call to undefined function Joomla\CMS\Language\simplexml_load_file(): Call to undefined function Joomla\CMS\Language\simplexml_load_file()

I think it is about SimpleXML but isn't that installed with php-xml?

I did install php7.4-xml

[sozzled]

The FPA report (even unreadable as you've posted it), says that your J! website is running J! 3.8.7. OK?

The version of ../libraries/joomla/filesystem/path.php (written for J! 3.8.7) was released three years ago. That file worked with PHP 7.0 and PHP 7.1 (which were available around that time), that file probably works with PHP 7.2 and PHP 7.3; PHP 7.4 is completely different. That file doesn't work with PHP 7.4 (unless you change it). The easiest approach to fix your problem would be to update your outdated J! software.

There is nothing more to be said about this. It's your choice what you do next.

According to the FPA results, the PHP extension XML is missing:

Potential Missing Extensions :: xml | mbstring

[ArtistScope]

Potential Missing Extensions :: xml | mbstring

I installed mbstring but the report is the same. I am thinking that i have mixed modules that don't recognise each other, for example:

Code: Select all

php 7.4.18-1.el7.remi

php-json 7.4.18-1.el7.remi

php74-mbstring 7.4.18-1.el7.ius

I think it best that I start again by removing all PHP components and re-install PHP 7.4 again.

Can someone please please list all of the PHP modules that are needed for Joomla 3.9?

And the best yum repository because the last one that I used did not include everything?

[ArtistScope]

Problem solved after manually removing old repos from /etc/yum.repos.d/ ...

Then re-installing PHP and modules from a repo that contains the complete collection for 7.4
