Cannot update Joomla extensions on Joomla 3.9.15

[MBButton]

I am trying to update my Joomla extensions using the update manager. I've never had any problems with this before, but after upgrading to J 3.9.15 yesterday I am getting the following error and warning:

Error
The checksum verification failed. Please make sure you are using the correct update server!
Error updating COM_INSTALLER_TYPE_TYPE_.

Warning
Update path does not exist.
Before updating ensure that the update is compatible with your Joomla! installation.
You are strongly advised to make a backup of your installation before you start updating.

I have checked with my hosting provider (Siteground), and the tmp folder exists and is writable. All other folder permissions seem to be correct. Siteground is confident that the problems are not on their side.

I have looked at other reports of a similar problem (mostly from about a year ago), but I don't see anything that I can implement to solve the problem.

I would be most grateful for some guidance. The extensions that I cannot update include:

JCE Pro
Membership Pro
Regular Labs — a number of extensions.

My FPA report is below.

Thank you in advance!
Bruce

Cannot update extensions

Before updating ensure that the update is compatible with your Joomla! installation. You are strongly advised to make a backup of your installation before you start updating.

Contacted hosting provider, checked tmp folder to make sure it is present and writable, checked folder permissions. Hosting provider assures me that there are no problems on the server side.

Remove the url from LiveSite in configuration.php.
Navigate to Components >>> Joomla update ... check for updates ... reinstall core files.

Error updating COM_INSTALLER_TYPE_TYPE_.

This error can occur if the type column is blank in one of the rows in the extensions table of the database.

Use phpMyAdmin from the cPanel provided by your host to run the following SQL query, where xxxxx is the table prefix in your database:

Code: Select all

SELECT extension_id, name, element FROM xxxxx_extensions
WHERE type = ''

In a similar case some while ago it was found that the plugin System - Regular Labs Installer had no type. After that row was removed from the extensions table, the message disappeared.

Thank you,Webdongle, for that suggestion. Unfortunately it didn't work.

Thank you, toivo, for the suggestion. I have checked the extensions table but there are no rows where there is no type specified.

Try updating one extension at a time then tell us which extension is triggering that error.

Try updating one extension at a time then tell us which extension is triggering that error.

Thanks, Webdongle. All of the following extensions trigger the error:

AllVideos
CoalaWeb Gears 0.5.8 - CORE
JCE Pro 2.8.5
JCH Optimize for Joomla Pro
Regular Labs - Advanced Module Manager
Regular Labs - Articles Field
Regular Labs - Conditional Content
Regular Labs - DB Replacer
Regular Labs - Dummy Content
Regular Labs - Modules Anywhere
Regular Labs - ReReplacer

So it seems to be something related to Joomla rather than to any one extension.

Disable JCH Optimize for Joomla Pro and clear Joomla cache.

COM_INSTALLER_TYPE_TYPE_ is in Joomla language files but you have used Joomla update to reinstall core files. This suggests that it is a path issue and the Joomla language file(s) are not being reached. JCH Optimize has been known to cause that type of problem.

Webdongle, you really are going out of your way to help.Thank you; I appreciate it!

I have done as you suggest, but unfortunately the problem remains.

Use Akeeba to copy the site to localhost (wamp is a good localhost for windows PC) see if the same problem exists there.
