Joomla 4 - Sorry, an error has occurred. Please clear your browser cache.

Pierre,

I have the same issue. And it's keeping me from doing my work. I have to update a website form J3 to J4. The issue is big enough as it is that Themler doesn't provide us with a way to update the themes and now when i follow the right procedure i get this error.

I have also installed the Themler_J4PHP8_v559.zip that i found on this forum, but the problem is the same there.
I have also tried switching between PHP7 and PHP8, same problem.

I'm trying to get frustrated about Themler, and i'm thinking about taking other steps

When i look further on this forum is see that this error is existing for almost a year now. So @Themler it is time to take some action.

I can help you with testing and i have also added a screenshot of the console that might help. But it is not acceptable that this issue is in your software for that amount of time. It's time to realise that there are a lot of paying customers that want to keep using Themler (and not Nicepage)

Hello,

Do you have an answer for this problem?

Regards,

Pierre

I have now already converted many Joomla websites to J4. Each conversion to J4 brought the error message discussed here. For a long time I was looking for a solution and now I found a workaround that always worked for me now. So I could migrate all websites to J4 practically without problems.

My last project: Update Joomla 3 to Jooma 4.3.4 with PHP 8.1
Once the J4 update was installed, I did the following steps:

If you haven't done it before the update to J4: uninstall everything related to Themler (all templates, all plugins).
Now the first important step: in the path /domain.xxx/templates/manifests delete all .manifest files, except manifest.php.

Clear the cache on the website and now the 2nd important step: In this forum in a post the Themler developers offered the Themler version v559 for download, I still have this and this version is the only one that has always worked for me. All other versions, newer or older, always brought the same error. v559 however not.

So I installed v559 and Themler started without problems. In the folder path /domain.xxx/templates/manifests the themler-559.manifest file was also created. Sometimes it was necessary for me to install the same template ZIP file again, for whatever reason.

Maybe this post will help someone of you, at least I hope so!

All the best and good luck! Greetings

Hello,

When I export a template with Themler on Joomla 4 and then import it on another site, when I want to edit it, I get the message "Sorry, an error has occurred. Please empty the cache of your Navigator."

I tested on three browsers and it does not work

I spent a day redoing the whole template for Joomla 4. It would be nice if I could use it now.

Waiting for your help.

Regards,

Pierre
